Hmmm, both your and HM's replies sound distinctly possible. I have 2 power transformers (HT & LT) which are both horizontal, as is (you guessed it) the output transformer. However, I *think* the amp that used this output transformer before also used to hum so it *could* be an imbalance in the windings, except that if there's no HT or LT then that must mean it's induced...
I'll try moving the output transformer first - it'll be less work than the power ones. I'll let you know what happens...
