Philco 41-250 oscillator problmems
#1

I'm restoring a 41-250 with nearly identical symptoms as those posted Feb. 5 by another user. Only a limited span of BC band is available, frequencies are off and can't be aligned, Police band has only a strong local BC station on it, no shortwave. Pushbuttons don't change stations. I've rewired chassis and band switch, all tubes check strong, etc, etc, no significant change in symtoms from before to after. All oscillator coil windings check good, all wiring checks correct per schematic. I'm wondering whether oscillator issues is common in this model for some reason. If I have the corrosion issue in the oscillator coil it doesn't show in impedance checks. Any help appreciated - I'm at wits end, having spent weeks on this one!
