Title: Walrus Fathom no output
Post by: spoontex on October 27, 2022, 01:33:27 PM
Hi,

I've received a Walrus Fathom that doesn't power up. I opened and I found a burn / broken trace. I've fixed this trace and I have power but no audio output. So, I trace de audio signal to the FV-1 chip and I have reverb on the output of this chip ( pin 28 ), so I trace the output but the audio stop on R30 resistor. I only have audio on one side, the part that goes to the potentiometer doesn't have any signal. I de-solder the resistor ( 1M ) and it's ok. So, I need some help...
