That took care of those trimmers -- thank you, thank you.

All the rest of the tuning worked as expected except for the very last step which is the 53S trimmer (32-2376) for the discriminator (6H6G) at 1,000KHz in the broadcast band.  The magnetic tuning switch is turned on (PHILCO SERVICE HINTS & TIPS - NUMBER 33).  Turning the trimmer seems to have a little effect but not really predictable.

It looks like a person might hold the nut while turning the inside screw but without really honking on it -- which I haven't -- it doesn't currently budge, the whole thing turns, giving that small "fuzzy" effect.  I don't want to be turning the whole thing if it isn't supposed to turn.  But since I already have, my concern is that those tiny wires are broken and that's why I'm not seeing much tuning effect.

I've never taken one of these cans out or apart, but it looks like I need to open this one up.  Can the can be lifted for view/access without unsoldering and un-mounting the whole thing?

Does anyone know how this particular trimmer is supposed to work mechanically?

Thanks in advance...
