The Fuses Keep Blowing! - A Really Nice Bryston 4B NRB Power Amplifier Repair [Video 30]

Greetings everyone!
Today, we have a really nice Bryston 4B NRB power amplifier that came in for repair. The problem with this power amplifier was with one of the channels, as the mains fuse kept blowing up on the customer. After some investigation, we find the source of the problem and bring back this dinosaur to life. The customer was happy with the outcome of this repair!

Hello teammate!

I really enjoy the channel, but please get a tripod for your phone, I can only watch for a short period before the camera movement messes with my eyes.

Please invest in a tripod.

i remember repairing my 8B-ST, Bryston wanted $30 each for their "proprietary" transistors. i ended up buying MJ21193/94 pairs for much cheaper price. i prefer these devices than 1502x devices since their current gain is much more flatter across both NPN/PNP and collector current

Great video, my friend. You are very smart. Bryston makes some of the best amplifiers for the money plus 20 year guarantee. You're in good hands with Jesus watching over your workbench 😊
