EMAX II boots but no sound/no VU levels register

2016-03-14 by oracular@...


I just brought an Emax II rack back to life, sort of. I did the JM215 slim drive mod, and adapted and ATX power supply. It boots up, but so far I haven't gotten a sound out (or in). From the "VU Mode" page, it doesn't register any input even at max gain. If I do "force sampling" with audio going to the sampling input, then audition, I just get silence. Is this a problem with the analog PCB? I'm thinking reseating all ICs, and cleaning the contacts with deoxit.


[Later...]


While reseating IC10 on the analog PCB, I noticed that resistor R84 (the one right next to IC10) is burned. That can't be good.


Does anyone know the specs of R84? Alternately, a picture of R84 would do, I could work it out.


If my IC10 ADC is toast, is it possible to obtain a replacement?
