Hello,
My problem is a small but noticeable noise coming from the tube amp on standby. I don't know if i messed up a tube, due to the fact after my practice today. 4:00pm is when i last practice. Left home and got back about 8:30pm or so. I came back and noticed it was on stand by the whole time. The amp was pretty hot. i never noticed the sound before until today. It a noticeable hum, and it only comes on when i turn the whole amp on. Then put it on stand by...
The amp is HT 60
