I'm going to use the Lear tuning head to feed the 85 kc IF of the R-11a. My
big problem will be voltages. The R-11 uses 14 volt tubes, wired in series
pairs. That was for the plane's 28 volt system. I'll have to rewire them in
parallel and feed them 12 volts. I haven't looked at the Lear yet, but it
probably uses the same idea.



The ARC book shows the 12-24 volt re-wire options. The Type 12 system,
of which all that series is part of, was designed for both voltages.
Its not difficult, at all, to swap a few wires to change the voltage.
If you need the sheet, I think I can scan it into a TIF.
