Philco 38-10 Tuning Condenser
#1

Hello,

Working on a 38-10 where the tuning cap gears have separated. I have got one spring out that was jamming the ability to rotate the shaft but can't get at the other one. I have removed the tuning shaft in order to free it up since the center does nothing. Probably hardened grease. Any ideas on how to get the rest of it apart so I can get the one gear back in place and both springs back.

Thanks,
Dan

It is possible (but not always, depends on the design of the capacitor), but it is a very precise job.
It is necessary:
1) set to the minimum capacity position (fully extend the rotor from the stator)
2) completely unscrew the rear centering screw
3) remove all the balls from the front bearing
4) tilt the rotor and remove the axle from the front plate.
5) assemble in reverse order, generously lubricating the balls and other rubbing surfaces with Vaseline before reinstallation.
6) adjust the position of the rotor with the rear screw, checking for short circuit of both sections in any position.

If you want to work, lie down and sleep, and everything will pass.
