Triode as double triode

I have a Feliks Elise amp. It uses 2x 6AS7G (6AS7G is a double-triode) as power tubes, so 2 triodes for each channel. These 2 triodes are wired in series. I bought some 6C33C, which are single triodes.

I want to make some adapters so the 6C33C will work. How exactly should I wire the pins?

Should I wire the 6C33C cathode pin to both 6AS7G cathode pins or only one of them? How about anode? How about grid?

It isn't clear what circuit topology the amp uses, so changing the output tube could result in serious problems. Never mind that the 6C33C draws almost three times the heater current which the power transformer may not be able to supply...

I would leave the amp as is. If you really want to use the 6C33C, it would be better to design and build an amp for that tube.

I fully realize it's not made to use the 6C33C. I will be using an external power supply to heat the tubes. All I need is the wiring.
