Re: Help With Low Cathode Voltage (Tube Crossover)

Alfredo -

It's a bit tough to tell from the pic's, but I have some ideas...

I see the Red/Yellow (B+ Centertap) going to the OD3 but I don't see it going on to the crossover board.

Is the OD3 glowing?

Can you measure around 150v across the OD3? (Between pins 2 and 5)

What are you using as a "ground reference" when you measure -34vdc at pin 8 of the 6X5?
