"It's also possible to substitute a 6LF6 for the final tube, if you take the heater-power wire loose from the final-tube socket and put a 6-Amp rectifier diode between the wire and the tube socket. Pretty well cuts the heater voltage in half. "
Thanks Nomad,
Gotta dig around and see if have any of the 6LF6 tubes out in the barn. Does this have any positive effect on the drift issues with the 1011D? Decent radio, just won't stay on freq., doesn't wander much, but have to keep an eye on it. Placed a brooder light over the radio and that helped some by keeping it warm and cozy like a wittle chicken.
