I think this is the first restore/repair I ever saw of your's. I will hold all negative comments. I was glad to see your simple technique for testing the transistors on an analog testing meter.. Not so easy to do that on a digital testing meter. Your video kept my attention.

Looks to me like one of the many inexpensive amplifiers that cloned the layout of the Crest CA series amplifiers. No schematics appear to be available, although the lack of mica insulators shows that the circuit topology is not the same since the collectors are apparently grounded. By the way, there is a torque specification for TO-3P transistors, usually between 5 and 10 inch-pounds- significantly less than people tend to think. It has been mentioned already, but there is a reason why the original transistors failed. Checking the quiescent current in the output stage as well as running a sine wave test into a dummy load and looking at the output on a scope are worth doing.

bongkar abis nih heheheh

SIR YOUR SOLDERING IRON IS VERY DIFFERENT 👍👍

Installing power transistors without checking voltage bias is very risky. You might end up changing them again and again.

Super amlifer super very good video nice work very very good video sir thank you

I love it how mr electricity never wears gloves. Until the bucket of soapy water come out… 😉

Mr Electricity you work amazingly seems you knows the design and circuit configurations of the amps didn't see you label or marks any of the hook up wires .

A sua profissionalidade é incrível, parabéns pelo o trabalho muito bem feito. Sou aqui do Brasil da cidade de Fortaleza Ceará.

Dear Sir, thank you very much indeed for your always very great video and very educational. However i like to use a little brush for thermic paste And the electric drill seems to have too fast rotation. Clearly you were in a hurry ... i love your videos. When i will retire i will try some restoration work ... i love audio equipment deeply. Thanks again and kind regards, gino

Great, you are full fledged service personal keep it.

Macht immer wieder Freude einem Experten über die Schulter zu sehen. Großartige Arbeit!!! glG.

From Malaysia...👍👍

Hi nice amp indeed. It looks very well designed and also parts seem very well sized. Great job as usual. It is a pleasure to watch your repair videos Thanks a lot. Kind regards, gino

Great video ... but replaced all those shorted components ... all back together and flick the switch and Voilà !! works !! Surely there was abit of last minute oopsy in between ??

Good job definitly i wasnt gonna take all those wire apart..lol amp looks n sound good

I have so much respect for what you guys do...Gretings from Poland :)

Ok , very nice👌👌👌👏👏👏

Muantap👍sukses selalu kawan🔔👍 aku yakin kawan bukanlah kacang yang lupa akan kulitnya.salam kawan baru dari Bogor 🙏

super restoration mais normalement il faut mètre le volume a fond sur l'amplie après on règle sur la table de mixage

...applause, master job, it´s a pleasure to see this restoration...

It is a good work of restauration and a very beautyful amplifier.

Hola saludos mr Electricity te felicito es un buen trabajo muy bien hecho así habían de trabajar los que ven tus videos saludos desde puebla pue.Mexico

thank you so much for this video. I wish I have the confidence and technical expertise.However, looking at this video helps me a lot gain more insights and understanding on how and where to test some basic troubleshooting area of known issues. It looks easy in the video but they aren't. I am now a big fan of your talent. God bless you Bro ! Keep doing what you love to do. If you need a partime apprentice in the weekend. I would like to apply.😁 #loveelectronics #cebu

What kind of cleaning chemicals are you using for cleaning all the electronic boards????

just loosen the screws with a hand screwdriver Otherwise you can damage the screw thread

Bravo mr on a besoin de vous ici merci

Mr E, theres no way that you know how all that goes back together. I'm convinced the 2nd half of this video is just the 1st half running backwards.

Te felicito por darle vida a este buen ampli, saludos cordiales Nezahualcóyotl México
