Hey internet, I just finished refurbishing this GFA-555, and the customer opted to go without the BFA-555 Smart Soft-Start Power Supply, so if you’re wondering what you get without this option, here it is! I do install some Capacitor Hats to replace the crusty originals. The original power supply capacitors were replaced with Kemet ALS30, 22,000uF, which is about as big as you can go without a soft-start. (Or the switch will spark too much and the fuse may blow due to the in-rush current.)

Invoice on this one was $1210.

Dust is attracted to high static voltage, dramatically illustrated here on the underside of an Adcom GFA-555. These dusty traces are at only 80V potential, but that’s enough to make them dustier than surrounding traces at lower voltages.
