Hey guys,

Long time lurker, first post here.

I need a little help.

I received a single channel TWIN module today (Merry XMAS to me!) that doesn't work.

It will pass signal if I crank the amp, all the knobs appears to work, except for one thing.

The tubes do NOT glow, they seem to be getting some juice because they get slightly warm, but nothing like my other modules. I've tried swapping tubes so that's not it.

Assuming it was working before shipped, I figure a solder joint needs to be reflowed somewhere.

Anyone have suggestions on where to start?

I emailed egnater, but being saturday and the holidays I'd rather PLAY my new toy on Christmas rather than stare at it wishing I could!

Thanks.
 
Update: I put shortplate tubes in there and they DO glow, the long plates I had in before were just hiding the fact. So I don't think it's a tube problem.

However there is still VERY low sound. If I CRANK the amp I can hear the guitar ever so slightly and the tone knobs work. The only knob that doesn't really do anything is the master.
 
I had a similar problem with a Voodoo Lab preamp,and it turned out to be just, that a volume potentiometer.

It appears it was a bad pot. The old one didn't even measure! I put in a test pot and the module appears to work.

Thanks to Bruce for his assistance. Now all I need is a replacement so I can put in the proper pot.
