Philco 97 - RF problem... HELP!
#11

In any case, using any of the above should make an improvement in freeing up the motion of the vane.
Thanks for the tips - I have used some solvent, and I thought the problem was still wax... but I pulled it all down again and checked - it seems to be a combination of a couple of things... I can only get the AVC voltage down to about 4.5V on a strong station now (I was able to get it close to 2V when I started)... so there is too much voltage on the coil to keep the vane straight.  And, I've also just noticed its sticking magnetically, not with wax.  I remagnetised the bar magnet because it was barely able to lightly hold the tip of a jewelers screwdriver... its now a lot stronger at the tips but weak in the middle... I may have overcooked the magnetising process?

Any chance of some more images.  Say a full one of under the hood.     I got me one of these which is outside the US. but designated a model 98 series.1.   I believe my chassis to be a model 97E. but no marking plate on it. Different cabinet to yours though.

Do you know the history of Philco there in NZ. eg.  Did they have a production plant or just import to NZ from the US or via AUS.

Regards.

Will.
Hi Will, I read somewhere that the 98 was a UK model?  Here in NZ, Philco was imported lock-stock-n-barrel until around 1936 I believe... after that (taxes?) they were just imported as Chassis' and locally made cabinets were used - in a similar style to the US cabinets.  At some point after that Dominion Radio and Electrical Co. (DRECO) was started here to design and build Philco sets in New Zealand... So yes, we had Philco manufacturing here but the brand died off (was killed off?) in the 50's some time when DRECO started pushing names like La Gloria and Majestic (often on very similar sets).  Thats my understanding of the history of it here... its probably not quite right, but it should be close...

Photo under the hood (post-repair so you'll have to imagine it with more dogbones and waxies in there):

There are no personal problems that can't be overcome with the liberal application of high explosives
