Hey guys, my amp is giving a pretty annoying whine right now. It's possible it's tube related, but the oscilation in the sound makes me think it's fan noise. Is there a fan in the Triple rec, is it possible/easy to replace, or do you think it's just tubes? The noise is still there when the amp is in standby as well.
I put new tubes in when I bought it a year and a half ago, so it's due for a re-tube, I've just not experienced this kind of noise coming from tubes before.
I know the older triples did not, not sure about the reborns. But I would start changing out pre-amp tubes, might be your phase inverter tube.
