I recently bought an amp needing repair. It is a fairly recent piece, probably manufactured in the mid 90's. Apparently someone decided to recap it. To their credit, they made good choices in capacitors, mostly Nichicon PW in power supply and Gold Tunes in the audio.
However, as I disassembled the unit to assess what needed repair I saw damage caused by poor workmanship during the recap. Here's a pic:
The board has caps on both sides. You can see here where the pads were ripped off during the removal of the old (and considering the age, probably still good) filter caps. Pretty sure these caps on the bottom aren't filtering a damn thing.
I'm going to have to examine all the boards looking for other damage. It's a crying shame; this is a quality high dollar amplifier. I purposely haven't mentioned the make and model, as I bought it in BarterTown and I don't wish to insult or embarrass the previous owner.
So the purpose of this thread is to say if you don't have the skills or the proper tools don't damage something while trying to improve it. So take the Hippocratic Recap Oath: First, do no harm!
