I've got bigger transformers. What voltages do you need?

Why not a Pullen mixer? More gain, good strong signal capability. A dual 
triode with a 300 mA heater for the mixer and a 6C4 or 6BH6 (150 mA heater) for 
the HFO, so there's no difference in power requirement. Just one extra tube. 

Let me know about your transformer needs. 520 VCT @ 90 ma work?
