Okay yeah, more of a deep clean than a renovation. The amp obviously worked before the strip down.. However still a good watch and definitely better than watching some crap soap with the wife ! 😂

[@faceless3239]

yeah forget all the other stuff he did like pulling all the caps and testing everything for continuity and testing all of the caps to make sure they are good. sometimes a good clean can make things work again so instead of being so damn negative keep it to yourself. "poked random contact with a tester" tells me that you have no idea what you are talking about too.

It made my heart feel so good to see cleaning completed BEFORE repairs were started. I watch hundreds of vids which don't even give a minor dusting before new parts are installed. I cant understand why any tech would start before cleaning. After my service ended in the early seventies I entered industrial maintenance work with some really top notch professionals who insisted on clean first which I maintained my whole 42 year career as an industrial electrician working in rubber, foundry, trucking and auto dealerships.

I see the two mains fuses are 16 amps into a PC board. Assuming you are in Europe at 230VAC x 16A total = 3,680 watts max. Leaving a little room to prevent fuses blowing every hour at full volume, let's say 12A working load. 230V x 12A = 2760 watts in from the mains. The amp is a direct coupled analog amp, so it's about 35% efficient to get great harmonic distortion numbers the audiofools insist on. 2760 x .35 = 966 watts /2 channels = 483 watts/channel....into probably 2 ohm loads. 483 into 2 ohms, 242 into 4 ohms, 121 into 8 ohms per channel.....hardly the 4KW RMS promised. 121 watts RMS will smoke most consumer grade speakers! Less than 2 ohms the lines of transistors melt but will blow the 16A fuses or pop the house breakers before the fire... Shhhhhh....Never mention math when selling stereos!

[@klonik79]

This is not an amplifier to use at home at 2x 2000W, and concert halls etc tend to have 25/32A outlets for these. At least they do here.

[@PlatypusPerspective]

@@klonik79 True, it's targeted at clubs, discos, cinemas and auditoriums etc, specs claim 3760W RMS @ 1%THD bridged into 8 Ohms, 2800W/ch into 2 Ohm, rated power consumption at maximum output 6760VA.

[@Reaktanzkreis]

The mains plug is US style and it seems the place got 115 volts mains. In US a 230V mains plug looks different. An amp of such caliber it runs in a professionel sourronding on 230 fused with a 32A outlet, such as CEE series plugs.

Big job thanks for the video. I just would try to turn on the piece before servicing it. Also, you need to replace those big caps friend they will leak soon. The glue you remove is crucial for vibration damage the solder points specially if they're sideways. All these is future proofing.

[@PlatypusPerspective]

That's a current model amplifier that's still available to purchase new. I don't know how long the model has run, but even if it's a few years old, little reason to suspect the reservoir capacitors. I agree he should secure the capacitors against vibration stress, the service manual for that model is specific about requiring that! Common sense too.

Just blow it out with air then take the garden hose too it. Just make sure it is 100% dry before plugging it in. I just got a pair of Peavey SP-2 ti PA speakers I am in the process of rebuilding. One box is missing the 15 inch Black Widow sub and needs a new driver for the horn. But I believe I got one of them dialed in with a fresh cleaning and some new shiny paint in places. Dude slow down on the bomb can paint. 1st three coats need to be light dust coats. Let it dry for 30 min then come in with a medium light few coats. It is not a race to see how much paint you can put on the case. Most spray paint is enamel and that takes a while to dry. When you pound it on it cannot vent off like it needs and with remain soft for a long time. 1st coat you should be able to see metal or sanded paint under it. really up into the third light coat. Once you got the mostly dry light coats you got a nice base to come in with the medium wet coats. A good three of them with dry time of 15-20 min in 65-70 deg. weather (Fahrenheit). Put in hours of work to clean up they unit just to paint it like sh!t. Ya see guys do that with hot rod builds. Put 10's of 1000's of dollars into a rod just to skimp on the paint and ruin it.

Good job! Modern lytic capacitors seem to be very durable, or weren't that old in this amp. I was also surprised all those flat cables with their connectors still worked despite only having control signals on them; too many companies working with tubes are using them for like 300Vdc up to 30mA, this will start failing like crazy in less than ten years... Diodes probably measured fine (didn't see the other polarity) but such bridges do fail with heat, soldering, etc. Oh, THAT VCA was interesting find, probably works for some kind of limiting or metering, can't say.

This is my take on it Fake as shit. e.g. every test on the toroidal transformers where done on the same multimeter settings, but lets pretend it was real, then every winding was burned out according to the test results. lol. The amp had no dust that normally builds up but was full of wood chip dust from the machines in the workshop. wood dust wont damage the amp and can be easily removed so good choice for fake crap. the capacitors could not be checked with that stupid meter lol another piece of crap. The whole thing is a staged fake video. The diode test was ridicules, All the new diodes failed the test and then failed again in the test in reverse , But this readings would be correct for a good diode if the diode was facing the other way. So there is fake stuff going on here. The bridge rectifiers all checked out as blown useless but the reverse fail wound be a pass. So I think the multimeter has one of these bogus repairs and they put the internal positive test lead to the negative external plug and the negative on the positive plug. Theis guys don't know the difference. This would explain the reverse readings they are getting . This means it is all fake . Also when they replaced the diodes in the board they all failed again because the other component's where also getting measured

A tutorial on how to create a fake device repair video. Take a working device. Sprinkle sand, dirt into the housing. pour some water( optionally mix water with salt and cover some parts to rust quickly). spread the dirt in the housing. Remove the fuses so that the device does not start ( or put the damaged ones). Show that it does not work. Disassemble all components. Wash each component in turn. Paint some part of the housing. Pretend you are repairing something, use a meter that has no capacitance measurement to check electrolytic capacitors.... Put the whole thing together, start it up , show that it works. Most of the videos that are made by people from these countries are fake. I am involved in the restoration of antique and modern audio equipment, and as I watch such videos I can not believe that someone is fooled by such a scam. To repair such devices you need RLC bridges, distortion meter, an oscilloscope, a generator, a load, and many other measuring instruments to get the job done right. After the repair, the amplifier's operating points should be adjusted. This and other videos are ridiculous and so untrue.

@@BPantherPink are you kidding me ? Don't know how monetizing on youtube works ? The more views, the more money the author of the video gets. You make money by displaying ads during the video. He will make more money in a month on such silly videos than you will in a year.

I found it very funny putting the meter across the MosFets without removing, and also the varistor on the power supply ridiculous!!

[@pangibonlang2994]

@@DanHomeAtLast I consider your comment here is the best... Upon putting power on the beginning, knowing that it don't power up, then without any small trouble shooting first is a red flag already. And as your comment, you are correct. That is not the proper way to test it. i consider it as fake testing of a person that does not know what he is doing.

True

I'm not a hater I just fix electronic devices AMPs as well for the entertainment industry. My conclusion yep is dusty, not rusty, as I recon bit TLC and works. Second, you normally put a Sine wave to input give it a dummy load, and check on an oscilloscope for any distortion, cracking on nobs loose connections on board etc... Third caps you need to measure with a tool not a multimeter to have a reading for ESR. BTW for people that said you need to power this on via the current limiter. Some people do that some don't depends if you want to blow it or not. Some stuff if you put thru a 40W bulb will not work and if you put thru 100W bulb will work fine. Depends on the situation.

Между прочим, усилитель на 2X1800 Вт. Не хилая такая штука! Стоимость в России 359 000 рублей. Целое состояние.

Hello, I also restore old devices, for cleaning the circuit boards I use spray cleaner for sinks and bathtubs, it goes much faster, after spraying the foam, just rinse with very hot water or with a diffusion of steam. Even on electronics lamps it works perfectly, of course you have to dry then in the open air, or spray ethyl alcohol if you want to go faster!

[@brianraulerson5037]

I was thinking it was ethyl alcohol myself. Based on what I noticed in the rest of the video, alcohol would be a cheap, efficient, and available cleaner to use.

That's an entirely fake amount of dirt and dust. It's the wrong color, it's too evenly distributed. FAKE FAKE FAKE! Downvoted.

[@marklestermorala295]

In india thats normal HAHAHA

[@Brian-mp6bg]

That’s real dust, you can’t fake that

[@bobof673]

Wonderful video, thank you. It would be great to know what fluids, cleaning solutions, oils, chemicals, glues etc, you use each time. Im a restorer myself and keen to learn from you as you are clearly very experienced. Thank you.

[@kcsandelectronistzsolt7084]

Nobody has nothing to learn from this guy, just to make fake video, and foolish 10.000 people. He have no clue how to use a multimeter, and this make him look more silly.

Belo trabalho, 👏🏾👏🏾👏🏾 e tbm gostaria de saber qual o nome da música 🤝🏾

[@kumarsajal8400]

Unfortunate to see that this machine was first intentionally ruined just to make a restoration video. How fake restoration video has become an industry now

Понимаем, что это постановка. Но всё равно интересно.

For real, looks like he went outside and told his kids to play with it in the sand. Still shows he is capable of repairs but if he were an honest man he would have a business and not a youtube channel = )
