TA-15 Channel 1 Intermittent Hissing
Posted: Wed Jun 06, 2012 12:37 pm
Hey guys, I recently purchased a used TA-15 and noticed that on channel 1 normal there is an intermittent high frequency hissing that becomes more apparent with an increase in volume (and wattage). Now if I switch into top boost mode, there is no issue. I don't notice any issue in channel 2. There have been a few similar posts to this but i haven't seen a post on this exact issue. Any suggestions?
