Hello. I just joined yesterday. I saw a youtube video with Nelson Pass being interviewed and thought this sounded like a great resource.
I am currently taking apart one of my Adcom gfa 555 amplifiers. White fluid began leaking from the bottom and when I opened it, I saw that it was coming from the transistors. Or rather the thermal paste from the output transistors. In order to clean it properly and not damage anything, I have to take apart the rear a bit and I wanted to test things like capacitors and any other parts that are known to go bad. I was thinking that this would be the perfect place to ask about it, since I’d read that Mr. Pass designed these amplifiers.
If there is anyone out there who would not mind sharing some information, I would greatly appreciate it.
Please do not tell me not to do it. I
Am on here seeking information about this equipment.
I do not wish to pay a shop hundreds of dollars. They quoted me $200 a few months ago to change a fuse.
I decided to do it myself. Some weeks back, this particular amp had a burning odor coming from it. Not smoking, just like the smell of plastic heating up.
I’m also building some external crossovers for my Magnepan speakers. Still waiting on some parts I ordered a couple of months ago.
I recently purchased a digital multimeter, a soldering iron and yesterday purchased an lcr meter.
Thank you very much, in advance
