Pentode/Triode switch on a DC30

Post by nee »

Greetings!

I installed a pentode/triode switch on the power tubes of my DC30, and I love the added versatility it gives the amp.

The DC30 also has a Hi/Lo power switch, which switches out two of the four output tubes. I've noticed that when I'm in triode mode, there doesn't seem to be any volume difference between Hi and Lo power. (The difference is very obvious in Hi power mode.)

Given that I may have something wired incorrectly, what voltages in which pins should I check to make sure that two tubes are indeed being taken in and out of circuit with the "Hi/Lo" switch?

Do you have a schematic for that triode switch. I might try it on a Liverpool.
I've got blisters on my fingers!

I just made it up as I went along based on what I've read on this forum!
