Hi, how could i get bithdate of my Les Paul Classic Premium Plus ?

First thing you should do is to get a copy of the McIntosh service manual. In it you will find a resistance flow chart it is for the service man and is very concise and will get you straight to any abnormalities quickly. The biggest failure with these and any old tube equipment is the power supply caps. The can caps in the 240 main power supply are 60 years old and should be replaced on merit alone, not to mention the fact that good quality 105 C modern caps are WAY better in every respect than those old multi can caps. I agree that the carbon resistors need to be replaced with like resistors, but be sure that the max voltage rating is high not the 200 volt ones that are common nowadays. The "bumble bee" caps are special too and should be thoroughly tested out of circut. With specifically the many McIntosh repairs I've done I have found that a fair number of these caps while operating fine were way off of value and when in testing them dynamically found that some have a much higher internal resistance. McIntosh equipment uses very high quality parts and it would be easy to degrade both sonics and reliability with Inferior parts. When I've replaced the bumble bee caps I use Atom Sprage polyester caps as they sound closets to the original ones. Also when you can find them the Spraig vitamin Q work well. Pio caps are great and new stock Russian ones seam to be of excellent quality, however they can change the sonic character of the amp. While this is good for voicing tube guitar amps for customers I would not change the sonics unless requested. One wants guitar amps to have different types of voicing, hifi amps should remain faithful to the original signal. This is a significant distinction between guitar and hifi amps. The McIntosh 225, 230, and 60 all have proprietary cores in the output transformers and are all wound on McIntosh manufactured winding machines and yes they are exceptional units. Oh and I haven't seen a single bad germanium diode in all the McIntosh units I've worked on while I have seen quite a few bad ones in other equipment. Mostly I replaced them with 1600 volt piv hexfred fast recovery diodes mainly because I had a role of them. Also on the 240 I try to find JAN 6L6's that have a 25 watt dissipation instead of the standard 19 watt tubes. Great video, just my two cents worth on these butifull amps.

White lab coat is a hoot. Probably wears it to bed.

I’m looking at a 2001… is this the same quality? Or could the advertisement be a typo?

These were weight relieved?

Not the part where bass, treble and balance bulbs were changed, but many minutes showing how you take the screws out 🙄🤨

hello, what is the brand name on the green coupling capacitors? thanks for your video....

I have a 2004 version of this exact guitar in honeyburst, I bought it new! I have just swapped out the original ceramic pickups for SD Pearly Gates, and am totally delighted with the results, it gives it a more vintage sound/feel/look.👍👍 I was interested in the wiring change you made in the video as that could further enhance the sound & would be a good match for the pickups! Thanks!👍👍🎶

Appreciate that you noted importance of good solder iron with adequate heat (and tip). You could do another video on noting all the solder joints on the board that need a redo. I wish I learned this early on. I once replaced wiring and seloector switch in my Les Paul and later had problems from bad solder joints due to cheapo ppencil point solder iron that wasn't up for the task.

Love your channel ! New sub here from Quebec !

I beg to differ, to some of us these are very collectible I have 4 from 95 alone premium plus tops and one quilt, another 3 being plain tops. There were only 2 black ones ever produced. One for the Gibson brochure, and one for a collector who had to have it. He collected all the colors they made at the time and to complete his set he needed the black Gibson agreed to make it for him. That is the only one that ever left the factory in black. The brochure one is still in the Gibson vault.

That amp at the beginning is not the 2210. At the end you show the 2210, what's up?

The 250pf cap on the paper&oil caps is that on the end that's grounded? And what does that cap do? Thanks great video.

That's a depth mod on the feedback resister he did

I own a 1995 Les Paul Classic. bought it from sam ash in NYC. one of my best guitars. When i was younger I loved the high gain ceramics 496R 500T but now I'm thinking about swapping for a more vintage PAF hb. and upgrade the volume pots to 500k while at it.

So this is a mojo tone kit amp with a few upgraded caps. From my experience, it's much less expensive to compile the parts yourself , you can end up with higher quality components and spend less overall. It's certainly easier to just order a kit, though. I'd recommend a kit if you are new to building amps. If you want to find out what's under the mysterious painters tape, you can google a jtm45 layout diagram or schematic. There's no magic sauce. If there are differences under there , it's not a jtm45. Maybe it's a jmp of some sort.

Is that a mojo tone kit amp?

I have reason to believe this guy has no idea what he’s talking about

😬

'Here in California' 😂

Neck pickup was a 496R I believe.

What a beast! Love that point-to-point wiring, although the soldering is obviously by an amateur, using way, way too much solder. Great materials, and elegant chassis layout nevertheless. 👍

how many A of the 20 ohm thermistor are you using?

One thing I recently noticed on my 1999 LP classic is the nitro finish on the headstock is starting to crack, adding character to the guitar.

I'm not very good myself, but sorry - I see a 1/2 mile of wire in there that just looks like trouble. It also looks very much modded at the start.

Great video bro. At the beginning you said the Les Paul classic measurements match several of the 1960 examples that you have had your hands-on, however you didn't specify which measurements. I would be interested to know. I love the fact that these have the small pin bridge that goes straight into the body VS the grommets/ferrules. These Classic models are probably the last time Gibson will ever offer that small pin option on a guitar less than $6500 from the factory. Both Tokai and Edwards LP's offer that option and both are extremely high quality if you can live with a non Gibson name. I can. I had a 2006 Les Paul classic honeyburst plain top of course, but I could not live with the green frets! Gosh they were awful, what was that about? I just got a 1997 classic shipped. I separately ordered the "Retrospec Exclusive Series Cellulose Nitrate Les Paul Fingerboard Inlays" from Historic Makeovers. So that will fix the green issue. The non-vintage correct wiring doesn't bother me, I always change that anyways using more modern shielded wire, potted pickups, push pull pot on the neck so that's a wash. I'm more concerned with the look outside the cavity. You didn't talk about the Gibaon water slide logo or the printed on Les Paul decals for certain years of the Les Paul Classics. I thought that was something pretty interesting, that might make this collectible one day. Gibson can give us the small pins on this guitar. But they couldn't give us everything.

Hey Dude! Long shot here but i'll try anyway. I have the same receiver but mine is having a lot of pops and statics on the right channel. Sent it to a guy but couldn't fix it. The pops still sound no matter if i crank the volume all the way down, also the balance doesn't affect it at all, if i only let the left channel on, the right one cracks and pops. Bass, mid and treble do affect it. Do you know what's the problem here? Varistors? Caps? a short somewhere? I love this receiver but the cracks are quite disturbing. Any help is appreciated. Thanks!

Looks like there are some of those cheap silver mica caps. If they cost 50 cents each then you are asking for trouble, speaking from my own experience with those caps.

I own a 2000 one and it’s my main guitar. They are the best les Paul’s ever made other than the originals.

thanks for sharing, Preparing for my own restoration of a SuperTwin Reverb (an odd one). This video really helps in preparation. BTW, Your link to the website if broken. I was wondering which deoxit versions you use for what parts. Also, there seems to be a lot of wax on the older boards. I heard that with older amps and micro dirt collected in the wax you can get DC current passing between components. Whats your stance on it.

Than

Where is your shop?

what power tubes? kt66?

Dude! The word is "te-non," not "ten-yon." Also, it's "po-ten-ti-ah-meter," not whatever you're saying. Peace.

I’ve heard that the wire runs can really affect the sound/noise. Is there any truth to that?

very Friedmanesk!

I really liking that up grade for my 97 classic LP

Somewhere in Europe I use Bassman blackface 1995 , lead guitar man use Jaguar guitar and Twin blackface.

Sort of 2204 preamp with sort of bass specs values mixed and a rc circuit on the NFB . Not a jtm45 at all

I think gibson hit it spot on in 2005 just before the VOS.. the R8/9s were simply amazing,, and true spec. Much more detailed guitars i think

When Guitar’s stop being, well, guitars to be played by guitarist and more collectors items, and collected by collectors for the sake of collecting expensive things. I kind of knocked the wind out of what a guitar is really meant for, and that is to be played and to be heard, and in my humble opinion, not on some wall just to be started at. it defeats the purpose but it’s your stuff and you could do what you want with it as for me, I can make a guitar that sounds and plays just as good if not better than any last Paul ever made and yes I will keep on rockin

The og def leppard was much appreciated, this is the whole reason why I just want to build one

From what I understand, the problem with the selenium rect is that *IF* it fails it releases toxic fumes, so it is better to change it just in case

Thank you for this helpful and informative video.

I too live in SB and Seymour Duncan’s warehouse re-wound one of my red bobbin Strat pickups for me. I need to locate your shop to install the 50’s wiring kit I purchased from Emerson Custom for my 1992 LP Classic. My biggest question is about weights. My 92 weighs 9lb-12oz. Can you tell us what your 97’ Classic weighs? I’m so curious! And can you tell me/all of us what the 5 original 1960’s that crossed your bench weighed? I also have a 1999 LP Classic plain top in honey burst that weighs 9-1/2lb. You can see this one on my KZbin videos. I like to study/play Fleetwood Mac unique covers exactly like Lindsey Buckingham and I video capture close to the fretboard slowed down a bit to teach/share how to play them. That 1999 Classic sounds so good, I am afraid to change anything else to it. It has Wolftone Dr Vintage pickups and original wiring. I’m guessing 300k pots etc. I’d like to send you a photo of my 92’ Classic Honeyburst. It has a modest beautiful flame top that like yours, may have been rejected for a higher priced model? I hope you can reply to my weight question? I wonder how the tone is closest to original’s based on weight’s. 8-1/2lb to 9-1/2lb vs heavier bodied LP Classic’s? Thank you!!

I enjoy my Sherwood S-7700 nice sound. Thanks for sharing the nameplate mine is older but not by much. 733599. Wish it was a Prime number but oh well.

Sounds great but doesn’t sound like a JTM45

I bought a 95 classic, new in 95. I will never sell it. I just take the pickups way beneath the strings to get a more vintage sound, or close to strings for high gain screaming. It’s by far the best guitar I have. I am amazed they still don’t cost that much to buy second hand

I just found you great video I'm new at this and I'm getting ready to start my first 50 w Marshall I have two years electronics training from Vo-Tech School

Were are you located In Cali Éric??
