2-ch Dual Rectifier help

[Brian D]

Hey guys,

I have a Dual Rectifier Rev F 2 channel, and as of yesterday it started having problems. I was playing and all of a sudden i got a complete stoppage of sound. After that, i found there was a dead powertube, so i took that one out, and ran 2 power tubes at half power. That worked for about 20 minutes yesterday -- once I got home, dead silent again (you have to dime the amp to get a very quiet amplification of your playing)

So i went out and bought new E34L's, and it was working for about 10 minutes, and then, once again, it cut out completely. What do you think is wrong? Preamp tubes seemed okay when i checked them, but i'm not ruling them out.

I hope you ran half the ohms when you ran the recto on 2 tubes

Does it completely turn off? or just go silent?

To a mesa dealer you go!

The preamp tubes on your amp are relatively new. They shouldn't be out at all. (used to be my amp.)

I did.

It just goes silent, it's not like the amplifier loses power.

Sounds like a screen grid resistor gone bad, a plague on many amps!

Doubt this will help, but I'll just post it for good measure.

If you have fresh tubes and everything is connected as it should be and you are still getting no sound, go to an amp tech. If there has been no output, your capacitors could be holding a lethal charge and unless you know what you're doing in there, you could end up with a new hairdo.
