Hi,
I have a Zen rev. 2, I had it running on 1.3Amps because with the Aleph-feedback I get 2A which is the limit for my heatsinks.
Because this sounded somewhat weak I decided to rise the current to 2A again, making 3A with feedback.
(I made a switch for the feedback via relais and a fan)
So without feedback it's fine, but when switching feedback on, I get a very high feeping noise (inside the amp!).
So I guess this is not the usual oscillation, because it is in the audible range?
What can I do about this?
thanks
martin
