There's only 5 parts that are in play here; the tube, C2, R2, tuning capacitor and oscillator coil. The first three have been replaced and I assume that R2 was replaced with a 47k resistor and C2 a 250pf capacitor. I also assume you have scrubbed clean the tube socket pins and reflowed the solder in all the connections. No band switch to clean. So now we're left with the L and the C. It sounds like you have the correct section of the tuning condenser, the one next to the speaker, connected to the oscillator circuit. And maybe the trimmer on the tuning cap needs to be taken apart and cleaned. Most of us on the Phorum have seen or heard how delicate 70 and 80 year old rf coils are. If the resistance readings are off then so is the inductance. If the oscillator is running at the wrong frequency then these are the things to look at.
