Single triode instead of double triode?


2015-12-03 1:23 pm
I have a Feliks Elise amplifier. It uses 2x 6AS7G (double triodes) as power tubes. The two triodes in each tube are wired in series, so 2 triodes for each channel.

I recently bought some 6C33C tubes, which are single triodes. Now I want to make an adapter, so these 6C33C will work in my Elise.

Problem is: I'm not sure how to wire the pins exactly. Should I wire the anode from 6C33C to both 6AS7G anodes, or should I only wire it to one 6AS7G anode and leave the other anode alone? Same question for cathode and grid.
