Philco model 43
#8

Well,I got back to this set and I replaced the power xformer so the plate voltages are close to where they should be{245v vrs 160v}. I hooked up the signal gen. and set it on 450kc and got nothing. I changed it to 460kc and got plenty of signal. I stopped there because the instructions were a bit odd. They want to set the oscillator to 175kc and I think they want you to leave it there when you align the set at 700kc and 1400kc{ the 4th and 8th harmonics}. Why not change the oscillator to 700kc and adjust the 700kc variable cap. for 700kc and do the 1400kc {on both bands} the same way? Thanks,Mike.
