distortion from DAC-AH after passive and battery mods

post #1 of 2
Thread Starter 

i did the passive mod and battery this weekend and now i have heavy distortion mostly in the mids and highs, is it possible i over heated something when removing the rectifiers or when i soldered the caps on?  Also i followed this pic that had the caps hooked up to r36 and r35 then i saw another one where they used c12 and 13 i tried both.  Im using dayton 2.2uf 1% caps from PE.  the dac is a older one that runs at 8v(lm7808).
