Hi nice bgw i have had many bgws in the 80s we use to install them in clubs i am a electronics tech for 40 years repaired a lot of audio and video watch a lot of your videos very interesting keep it up and keep safe Thank you
That old fan sounds like the bearings are a bit dry hence the jet engine sound (took ages to spool up to speed and dropped off like a stone when the power was cut) like you say though probably end up with a modern fan that was quieter out the box.
That is an impressive unit of power. I never saw one and noticed the 21000 microfarad caps on the power supply. Serious filters and a wall of TO-220's. Nice job!
That fan is knackered! There's no soft-start that I saw and it took a loooong time to spool up to full speed. Great video. Impressed at how quickly you narrowed in on the problem. I'd recommend that the customer gets the fan changed out though. I wonder if that fan is partially seized, and hence pulls more current through the 300R 20W resistor than was originally intended, and hence took the resistor out?
That fan motor seems like it takes a l-o-o-ng time to spin up to full speed. I wonder if there is something wrong with it... oh well, he'll probably want to replace this one with a computer fan, too.

Love the repair and the sound of that fan. Old school electronics

That fan sounds like a air raid siren 😂
I have several of these yet to be gone through-darned good info to have!!!!
What a beast of an Amplifier!
Great repair and nice vid! Thank you.
Wow. I had no idea that touching a TO3 whilst powered would give a nasty shock. Thanks for that info. It might have saved my life one day!

That's a beastmode amplifier 😀
nice job
I like these video's
I heard that fan spin up, so I went and got my luggage.
That fan has a great motor sound though
Maestro!!!!
5 seconds in during the header: Well effin' A alright. Interesting title. Let's see.
Wow I'll take two of those amplifiers
