hi gents; I have a K200B4 that I have been running with the PC403 preamp board disconnected because it was inop when I got the amp. I took a look at it lately and found the transistors Q400 and 401 had been replaced by someone who did the job bass-ackwards. I replaced these two trans. with suitable replacements installed correctly and the channel is now working but there is a bad buzz in it. I measured the dc at the output and found .033 vdc there. Is that too much, not too much or ???

thanks, jack
