I reckon its to do with the valves warming up, but was wondering if it was a more serious problem.
Its more of an annoyance than a problem though!
PS
To those who were following my progress with this amp before, thanks so much for your words of wisdom- ive learnt a ton from this site and saved myself tons of money fixing it myself rather than sending it off to a tech 
NICE ONE! |
In standby the only thing pulling current is the heaters in the valves. I wonder if this could point to a possible power transformer going south...there's no way sound could be coming through the speakers in standby mode unless the standby switch itself were bad and was somehow arc'ing internally. Where does it sound like it's coming from?
