That's awesome, Shane. Looks like a great job! I like the way you ran your wires, nice and clean. Bet it helps with hum reduction too.
Hey, remember that Nelson Audio amp that UPS dropped about 3 years ago? Did I ever tell you what happened to that after you shipped it back to me? I guess UPS paid the claim to Frank, and you and he settled. But the broken amp just sat there. UPS never collected it.
This weekend, I got tired of having it around collectimng dust so I opened it up to see what the matter was. Three large power resistors were poofed and on closer examination, I saw that some hand-wired parts in the power supply had shifted from the impact and were touching. That caused I high current short. So I moved those components, replaced the power resistors and the cracked tube. Works like a charm!
So I decided to touch up the paint where impact scratched it and even swapped the electrolytics for cerafines. It now has a second life!
