Hey all! New 553f user, long time builder/DIY'er
Curiously, I'm running into a wild problem on my first 553f Rev B build; PR6, the 10 ohm resistor on that (I believe) sits on the positive keeps frying! I've replaced it, switch opamps to a known working one, and up in flames again! I'm hesitant to keep trying as I don't want to damage anything else, but I'm at a bit of a loss! Diodes+Caps on the PSU rails are fine, Transistors on the followers/DT07 are oriented properly, I'm at a loss! Any help would be appreciated <3
