As far as bypassing the Rectifier Tubes with the switches on the back, this made no difference in my hum. It still hummed when the switches were set to Silicone Diodes. However, it was still the Rectifier tubes causing the noise. The noise was coming from the amp itself, not through the speakers. Not sure if this helps, but it's worth replacing those tubes (if you have them) as a quick test.
