In Reply to: Re: H/K 430 not working - need help posted by JWFokker on March 1, 2007 at 15:33:24:
a failing or bad driver or output transistor (or transistors).If the former, it could be related to cables or possibly even speakers.
If the latter, professional help is indicated.
N.B. The symptom you describe is NOT GOOD for your speakers. There may well be some significant DC getting to them. You can check with a DMM or VOM if you happen to have one.
One possibility for troubleshooting. IIRC, the 430 has pre out/main in jacks, no? If so, you can assess the function of the preamp and power amp separately.
all the best,
