FWIW . . . don't strip your speaker wires over your receiver or amplifier as you don't want any stray speaker wire strands falling into your audio equipment. Be careful dusting your equipment with wood cases as it's too easy to snag a bit of loose veneer and make it much worse. If you haven't used a piece of equipment in a while, exercise the buttons a few times and move the receiver tuner across the full dial a few times in order to make sure the contacts are clean. Never attempt to service your own equipment unless you know what you are doing as there can be very high voltage involved. If you have LEDs in your gear, you can rotate them in their holders to get brighter or dimmer light showing depending on your taste. Always make sure your equipment has adequate ventilation. Cheers!

My number one tip - If you buy a vintage amp or receiver without hearing it first, always check the speaker connectors with a multimeter set to read DC volts the first time you power it up. Don't connect speakers until you know there's less than 100mv of DC on the speaker outputs. If the unit has shorted output transistors and no protect circuit (more common than most people think) it can cook the voice coils of your woofers. Now if it's a tube amp or receiver, it's just the opposite - you need to have speakers (or a dummy load) connected. The output transformer blocks DC from reaching the speakers, so it's almost always safe. Playing tube gear with no load on the output transformers can be a very expensive mistake!

We used to have a kitten that would get on top of the turntable dust cover and paw at it, trying to get to the spinning record,. No amount of scolding or punishment would deter the behaviour. So, after taking the necessary precautions to protect the tonearm, I placed the kitten directly on the platter and started it at 45 rpm. It freaked out, took off like a shot and from that day on, never came near the turntable again.

One newbie tip for Yamaha integrated amps and receivers with both "direct" modes and a variable loudness control: MAKE SURE that the loudness control hasn't been turned way down before you engage the direct mode. The direct mode bypasses the loudness control, so you go directly to whatever the gain is on your volume control, which can be EXTREMELY loud if you were using a lot of "loudness".

For my vintage equipment speaker terminals (which are typically 6-32 flat head screws), I use 16-14 AWG, blue insulated-barrel, crimp-on Ring terminals or Spade terminals. If you are able to completely remove the screw, Ring terminals are best. If the screw has "spoiled" threads so they cannot come all the way out, then simply use spade terminals. You can also solder your wires after you crimp them, for a sturdier, low resistance connection, but be careful as the insulated barrel may melt back and shrink. This method has never failed me. I have had no issues with just twisting the strands tight and making a hook shape and wrapping it tightly under the screw head either, but if you keep moving around your amp/receiver, it's possible you can work them loose. I don't like the aftermarket ones that convert from a spade to a uninsulated binding post. They're most likely to come loose, rotate, and short out against the adjacent post. If they made them with insulated binding posts, that would solve the issue, but you still have the weight of the wires putting a torque on the screws, and possibly loosening them, so that's why I prefer the ring or spade terminals.

I worked at a cut-out record warehouse for a few years of my misspent youth and one of the chores we would do would be to "rebag" records which consisted of stripping off the existing damaged shrinkwrap and then sending them thru a machine that would wrap the record in plastic, seal off the ends with a hot wire knife and then send it through an oven to shrink the wrap tightly around the record. Now and then an album would get stuck inside or the cutting wire would come down on the album cover, which causes a straight-line burn across an entire edge of the record cover and the record. When we were really bored we would take unloved records and make bowls out of them by putting it through the oven 3-4 times to soften it up. If you see old sealed records with a shrinkwrap seam down the center of the back, there's a chance they've been sent through a rebagging machine by a dude who partied way too hard the night before and hates his day job, his roommates, and his life. Buy with caution and open it right away.

Some common mistakes I always see are people that stack components. I will see a turn table on top of amplifier vents. A common rule of thumb is to ALWAYS have at least 12 inches of space around any vents. With Marantz receivers, I almost always see circular socket scratches around the small faceplate screws because people are too lazy or careless when removing the faceplate with a rachet. Oh yeah, when removing a faceplate, people also use a screw driver to pry off the knobs, leaving horrible dings and scratches on the faceplate. Another one I always see is using WD-40 to clean pots. People also misuse deoxit when cleaning pots. If you use the wrong chemicals, you can completely destroy the traces. I recommend having a skylabs tech or Kevin make a video on what chemicals can be used on pots and which ones to avoid.

Those beautiful gold Spade lug connectors look like a short circuit waiting to happen when you bump something and pull on a speaker, as you mentioned. That's a pretty sizable torque arm rotating around a speaker output screw not really designed to secure with a lot of torque itself. Bump that wire using those connectors and you would have a short more easily than just using stranded. I would forgo the fancy, pretty and expensive gold Lugz and just used standard, insulated lugs which you crimp and flow a little solder after its crimped.

So maybe the wire strands to not touch when you move speaker cables, but the metal blocks touch! Put at least electrical tape over those blocks.

3:48 if you can't figure out the polarity using the speaker wire then face the two speakers towards each other about 1" apart. Turn on the music. If the polarity is wrong then the loss of bass gives it away. The two speakers are cancelling each other out and it is most noticeable in the lower ranges. Separate them and face them both forward to see the difference in bass output from when they were facing each other. The bass will come back which further signals that the polarity was wrong. Switch one of the wires and try again.

Might be a good idea to disconnect your antenna from your vintage receiver, also. It doesn't have to be a direct hit; a nearby lightning strike can induce enough energy to fry a solid-state front end (FET or MOSFET, especially). Also - if you live in a really dry climate, you can fry your solid-state receiver with ESD (Electro-Static Discharge) - commonly known as static electricity. Discharge yourself to the chassis before touching the antenna connections.

Most of the old tube amps (I also have a Fisher 400) were pretty forgiving when the speaker posts were shorted, just touching them together is unlikely to damage anything. This is because of the high output impedance of output tubes, as an example the 7868 in the Fisher is about 3KOhm (I have an old RCA receiving tube manual on my bookshelf from 1961, it was dusty). This is why there wasn't a strong reason to do a better connection on these amplifiers. The problem starts with the early transistor amplifiers, these amps also used the same speaker connectors, however the output impedance of the power devices is fractions of an Ohm, shorting these would cause all the smoke to come out. The amplifier manufacturers saw the problem and came out with better connectors. The only early solid state amps that I have experience with that didn't have this problem were the early Knight amps, they used a light bulb instead of a emitter series resistor, shorting them out would cause the light bulbs to light up. Pity the transistors were so noisy, otherwise the amps were kind of cool. I still have one lying around in a box, perhaps someday I will shift the input devices around to a low noise transistor and put it back in service. I would also note that most modern high quality amplifiers have incorporated current limiting, a momentary short will likely not damage them, however you will cause damage if you leave them shorted and operating as they will overheat.

Kind of a dangerous approach telling people not to worry with old tube amps outputs, because they are so forgiving.... A tube amp transformer dies silently in the background, while you don't realize anything wrong. Most old output transformers fall under unobtainium these days - and having them rebuilt and matched from scratch after toasting one of them accidentally by not worrying too much sure breaks most peoples bank.
@davidnorton573 Жыл бұрын
As I said touching them together is unlikely to damage the amp, however I wouldn't leave it running shorted. As far as unobtainium transformers I was concerned about that with my Fisher, originally Fisher set the bias high, and it had a lot of variation due to the selenium rectifier used. I suspect it was set high to account for production tolerance, otherwise crossover distortion could have occurred. I redid the bias circuitry and set the tube bias fairly close to the bottom edge of the spec for the tube, the whole unit runs much cooler, and I suspect the transformers will last longer than I will. @@werner.x

i learned the hard way that almost every company uses a different pin-out for their xlr to rj45 adapters (also tend to be referred to as cat boxes). i know that's more of a professional audio problem, but i use them for home audio to use the cat5e in my walls to carry the audio to whatever room i want from the A/V closet

A word of caution to all the cord cutters out there. I lost all my electronics to a lightning strike. Everything right down to the water meter. I believe it came in through the ungrounded TV antenna and went through the entire home. I now have the antenna grounded with 2 eight foot copper rods embedded in the ground along with a lightning arrester.

Another excellent installment. My brother earned his "Salsa Dish" T-Shirt ! Record storage of older releases -- PLEASE invest in some really good sleeves. I still am amazed when I see someone pull a disc out of a thirty year-old paper sleeve. BTW: sure is a "purty" L100 in the background.... Take care...Rip Oh yeah, those Minimus 7's again...

My turntable hangs from the rafters: sure does isolate it from the speakers, which are mounted on a C section girder attached to the brick walls, again, to isolate them from floorboards etc. Yes, I am 🤪

Experienced old head tips: Store lp's vertically and make sure they are not leaning left or right. Check and tighten speaker spikes and stands time to time as they really can impair speaker performance. Pull all connections (speaker wires, source cables, etc.) in and out periodically to keep contact surfaces clean for maximum signal transfer. Get a power conditioner!!!, I don't care what skeptics say the good ones really do improve the sound and will protect your equipment from catastrophic damage.(I KNOW BECAUSE TWO OF THEM SAVED ME FROM OVER $15,000 WORTH OF EQUIPMENT REPLACEMENT COSTS!!!). Seek out more tips from other experienced fellow audiophiles and periodicals,( STEREOPHILE, THE ABSOLUTE SOUND, etc).

@@ericschulze5641LOL but seriously, these power conditioner offer some protection, but that's pretty much all that they do, it's only a bunch of caps for static. That's all they do. But in case of a power surge, they don't do anything. Edit: audiophiles buy a lot of snake oil overpriced equipment, of course they will swear it makes a huge difference, because as the saying goes "it's easier to fool someone than to convince them they have been fooled"

Hello, I purchased a beautiful, perfect, immaculate Bang and Olufsen Beogram RX 2 turntable just before the pandemic. It is beautiful and perfect. it is really perfect for my useage. However, the other day, I heard a flutter on the left speaker. I believe the cartridge is passing away. The least expensive cartridge is around $300.00. Hifi is awful.

Hi Keven, love your videos, I think they and you are amazing. I have to apologize for being petty but speaker wire is stranded wire not braided. If it were braided it likely would not have the issue described in the video. An example of braided wire would be like solder wick.

In addition to removing the "outer" platter like on a Linn or Thorens, put some cardboard "shims" to just barely elevate the inner platter and keep it from bouncing up and down within the spindle shaft.

My top piece of advice is to trust your own ears. One person's bright is another person's dull, etc., etc.. We all have different components making up our hifi systems and no two listening rooms are alike. A piece of gear that others aren't happy with might work perfectly for you in your system in your home. On top of that, we all have different levels of hearing ability, the older we get the more our own hearing is likely to roll off at the top. Ever see a hifi reviewer publish the results of a recent hearing test? (I haven't). The sound as heard through your ears is what matters most.

Your comments on removing platters for transport was excellent. You then showed a Thorens TD turntable and missed the opportunity to point out that a TT like the Thorens has a suspension that allows the platter to bounce around, sometimes violently, in transport. The TD you showed had the MOTOR PROTECTION ROD, this can be added for ~$20. It is supposed to keep the platter from destroying the motor (for transport you'd still want to remove the platter or screw down the transport screws if present). Motors for these TTs have become very difficult and expensive to find.

Lightning arc's over everything, no protection. But when power gets knocked out, it's usually the surge when it comes back on that fries things. Also, I've lost more equipment from lighting strikes to the the network (DSL lines) than power lines.

Always wrap wire clockwise when screwing it down. This naturally draws the wire into the gap.

4:50 Not only should you secure your tonearm when moving it for longer trips, you should also remove the counterweight and put a piece of foam under it. That way you don't put force on the tonearm bearings when it's shaken in the car. 8:45 The turntable in between the speakers like that is just fine, if you use the appropriate type of turntable. For example the Technics 1200s I have are heavy enough to eliminate any vibrations coming in via the furniture under normal volume levels. Same for suspended turntables like an LP12. But a lightweight "chopping board" type of plinth that has no suspension either has no vibration isolation to offer, so those can't be used in such a configuration. 13:00 *Never ever tin your wires when using them on terminals!!* worst advice you could give! Under the pressure of a screw or spring loaded clip, the soldering tin creeps and it becomes loose over time, it can also oxidize - it's not a reliable connection! I can highly recommend using wire end ferrules or spade connectors. No soldering involved - very easily mounted by using just some cheap crimping pliers. Some advice of myself: 1. Don't pack records too tightly on a shelf. It will cause ringwear and split seams. Sometimes records can warp because of it. 2. If you have multiple cartridges on headshells, turn the phono preamp off before changing. Double check the preamp settings and don't accidentally blow it up by running an MM in LOMC mode! 3. When you get a new cartridge and you're all excited to listen to it, calm yourself down before mounting it. Free up plenty of time to quietly and calmly mount it. Don't rush...

Great videos. Loved the one on common misconceptions. A great analogy for the production chain of recording, mastering and manufacture would be cooking. If you make a so called fancy dish with the wrong or poor ingredients it's not gonna come out well. Whereas a good old Mac n Cheese which is cheap to make tastes great. It's all in the choice of ingredients.
@MarvinHartmann452 Жыл бұрын
If you buy spade connectors, wrap them with shrink wrapping because they will become loose over time and if they touches, it can, and will damage the output transformer, also, if you have a tube amplifier, never power it up with anything connected to the speakers terminals, it can cause oscillations and damage the transformer, and as you may know, it's a very expensive repair IF you find the part. Better safe than sorry.

Back in 1979 or maybe 1980, I was listening to my first pressing copy of "Some Girls" by the Rolling Stones. It was playing on a JVC JLA-20 which was in my opinion, a decent first turntable. I don't exactly remember the string of events that took me away from my listening pleasure but since the JVC had auto-return and the record was nearly over, I didn't think much about it. I wish I had thought about it because when I returned to my home, several hours later, I found that the auto return hadn't worked and my record warped from the heat coming up from the turntable. Now, I don't know why the belt didn't melt or why the rubber mat didn't melt or why the motor didn't blow up but my Stones record was totally screwed! So, don't ever leave a record playing, even if it's automatic.

Great video with a ton of good tips. Another mistake - acclimate your equipment. If your gear has been in storage (or you just bought it from a secondary market seller), bring it in to where you will be using it and let is sit for a few hours before plugging it in and turning it on. This will help with the longevity of the gear. The way I've always described the out-of-phase speaker issue is that when you stand in front of the speakers, facing them, the music will sound like it's coming from behind you.

I prefer old style thin spades atm, Id got some of the spade adapters and wass some tension on wire, perhaps the adapter wasn't tightened 100% and it turned/pulled into the one next to it and popped the fuse, thank goodness that was it and it was only out of commission until I got new fuses...scary.
