thats not a problem since tubes are supposed to be 12.6 volts on the heaters, this is lowered to 6.3 volts in guitar amps to keep the noise down. however the rectifier heater is usually 6.5 volts so you probably have them switched, but dont worry about it.

scott c sorry, rectifiers run at 5 volts.... -- 4/25/2002 1:15 PM
