if any of the front panel lights are on then the tubes will glow but if both front panel lights are off then the tubes will be off. also note that even if the unit is and still plugged up there is current going throught the preamp, so if you want to change tubes or play around inside make sure you unplug the unit (read the manual).
Unit off tubes gowing
Guys,
I have a Belles 21A pre-amp and noticed while dusting the tubes are glowing and the unit is off. Is this standard or
does the unit need servicing?
