Here is an attached schematic of an older Phillips SRPP OTL amplifier meant for 800 ohms.

If I substituted 6AS7s or 6C33C's what kind of power output per tube pair is expected?

Is there anything I should be aware of?

Or should I use EL509's?

Finally, do a balanced config to cut out that output coupling cap?

Anyways... its either this or a SE OTL amplifier...
