Philharmonic Tubes In Color With List

Scott:

When you are ready, put together a checklist requesting serial number, inspection date, and yes or no responses to identified production changes.  I have six Philharmonic chassis in the parts or restore shelves and two others that are easily accessible.  Armed with a checklist I am willing to inspect them one at a time and report.

Scott, mine does have red on the dial for coverage of 10 meters and up.
My photo section has a good photo of the dial only ... not sure how to link to it from here.
It would be great if you and Kent colaborate. I know he has serial number data.

That is good info Norman. 

I am not sure if Kent archives the details of the Philharmonics with his serial number list, but I certainly would be interested in creating a public list with Philharmonic dates and details- so we can put together a timeline for the production of these. 

Yours is a red dialer Ken?

Very interesting about the VR tube. There seem to be quite a few variations of the Philharmonic.
This one is the AM only, I believe, BOL with logging scale and no local radio station imprints. No remote and no tweeters.
After receiving the 1940 catalog from Kent I was surprised to see that my model was not pictured in it or on the price list. They only listed the FM model. I have found a date stamp May 1939 on one part. The catalog also showed my cabinet and indicated that it was exclusive to another model, not the Philharmonic.
I think we are doing radio archeology.

Scott:

The VR tube was moved to accommodate the remote control option.  Later in the run of Philharmonics, a universal chassis was punched for both the standard and remote models.  On this chassis, the VR tube was always up front.

Ken,

This is correct for the 9 knob version, but the earlier 7 knob versions had the VR tube at the rear of the chassis, behind and centered on the tuning capacitor compartment. 

I guess when they changed the Ultra Shortwave circuit, they needed to move the VR, so up front it went.

You are very welcome, David. I am only happy that you might find it of use. If I make any additions/improvements I will be sure to post it here.

Very nice. Printed a copy. Thanks for sharing.

While working on the Philharmonic I find that I often consult the tube diagram from the instruction manual. It is a bit confusing with all those branching arrows and such. So, I made my own diagram with an attached tube list. I also printed out all base (terminal) diagrams separately.These little aids make me a little less confused and better able to trace the circuit. Hopefully this will be of use to someone.
