Any tips on getting rid of the left channel hum? Tried a different (Electro-harmonix new) pre-amp tube, have a driver tube coming on Monday. I don't want to solder (Fitz mod?). I've ran it well over 100 hrs with just the pre-amp tube in and about 48 hours with both tubes in. It didn't hum at first, now it's really unlistenable. Thoughts?
