Gryphon S100 Amplifier Repair - Part 1. A close look at a nightmare.
Gryphon S100 Amplifier Repair - Part 1. This Gryphon S100 amplifier is in pretty poor shape. To make it worse, someone has been in here with lots of enthusiasm, and little to no care or know-how. It is a "dual-mono" power amp, and is really a high quality piece of equipment. The component choices and design is top notch, which explains the high price it fetched when sold in the 90's. The fault seems to be in the input boards, as becomes apparent when you look at it close-up. Someone has tried to repair this, and in so doing ripped up a lot of pcb tracks, and wired things up incorrectly. This is an attempt at getting the amp back to working order, with no certainty of success. Love the challenge (I'm an idiot)!
