My Dual Caster Died

[blown240]

I went to use my dual caster today, and it doesnt work.  Last time I used it, it was fine.

The circuit is a normal dual valve caster.

There are no obvious loose wires.
With the DPDT bypass switch off, the signal goes thru no problem.
I bypassed the switch and that didnt fix it.
It is for sure getting power since the tubes glow nicely
I tried different tubes.
I poked around with a dowel rod and no difference.

You CAN hear a difference in the static, when the tone knob or volume knob are turned. but not when the gain knobs
are turned.

I was playing thru my little gem, which works fine by itself.

Thoughts, ideas?

Thanks!

  Audio probe it.

Tubes glowing means the heaters are on. Not necessarily the rest of the circuit

I agree.   I was just using the tubes glowing to show that the pedal is getting power.  I tried different tubes, but that didn't help.

What he was getting at is that just because you are getting 12V at the heaters doesn't mean you are getting B+ voltage to the plates.

This.  Start at the input jack and work your way through from start to finish until you find where your signal stops.
