Noisy AM8012

Post by tufraniuh@yahoo.com » Wed May 29, 2019 12:41 pm

I bought a used AM8012 and it makes a lot of noise even with the filter closed. The seller claims that I broke it, but of course I connected correctly, this is not my first filter. What could be the cause of wild (white noise, hiss) noise with all the knobs turned off? I can try to replace the THAT300 and THAT340, will it help?

I think you'd better ask Rob directly via mail. His customer service is excellent!

I bought mine direct and recall pretty much that. Turned out the D.C. offset hadn't been calibrated and Rob helped me by email. Had a similar problem with an uncalibrated filter D.C. offset on another brand too.

How to calibrate D.C. offset?
