Having a look at the Philco 76
#7

Terry, make sure you replace the 35 you have as the detector with the correct 24A.

The plate detector needs a sharp cutoff tube to work properly. A 35 tube has a gradual (remote) cutoff which will produce a lot of 2nd harmonic distortion and low output, even though it may work to some extent.

If you don't have an extra 24A, switch the 35 with one of the 24A RF amps which should work fine with the 35 substitution.

Hi OSanders, Look carefully at the band switch. Turn it slowly and "wiggle" it around the desired band. ...MrFixr55 — 12:33 AM
