hey guy im new to the forum and have a couple questions about changing out my preamp tubes. my amp started doing some
high pitched squealing which means its time for new preamp tubes. iv never changed them out before and i was wondering ho u do this?
i have a triple rec and is doesnt seem to have as much gain as it used to what could be the problem with it? i have had it for about 3 years and have replaced the 6l6 tubes and the rectifier tubes but i have never changed the 12ax7 could this be the problem?
