Unit off tubes gowing

Unplug it.

Dave Belles is in NY and has a phone number.If you search the internet you will find a lot of information on your preamp.It may be normal for your preamp to have a reduced filament voltage when it is plugged in. Dave will be able to tell you if there is a problem.

The unit has been off for two days(no lights on front panel) and the tubes are still glowing. I'll have to contact my local dealer for possible repair.

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).
