Schematic for Dividing Network Box (Phantom)

[Joe Miller]

I believe this box goes with my recent Phantom Deluxe acquisition (rather than the Phantom Deluxe AM/FM)

Anyone know where I can find a schematic for it?

Thanks,
Joe

Joe, ...  Appears two amps are Philharmonic and one is Phantom. Two 12 inch speakers sounds custom.

The Jones plug changeover appears to suggest later 1941 production or the small 1942 production .

*overview

Phantom amps always have a pair of 6J5, pair of output tubes and pair of rectifiers. Philharmonic amps also have 6 tubes, but no 6J5s and always FOUR  6L6 output tubes along with a pair of rectifiers.

The amp with two 6J5s next to two 6L6s and the 5U4s is a late Phantom amp- for the FM/AM  receiver (or a late AM Phantom with logging scale). 

Amps with four 6L6's (and no 6J5s) are Philharmonic amps -  pointer and BOL amps briefly used 83Vs then 5Z3's.  But  in 1940, BOL Philharmonics added the logging scale both AM and FM/AM changed to 5U4s..

Earlier Phantom amps with two 6V6's, two 6J5s on the end and two 5V4s (or 5Y3s)  are earlier Phantoms without logging scale.

* From what info I have: the Spring 1940 updates to the Philharmonic and Phantom thus:

-added the curved logging scale window to the dial for both.

-changed both to 5U4 rectifiers. Changed the Phantom to (pair of) 6L6 outputs.

-changed Phantom field coil to match the Philharmonic 925 ohm tapped single field coil and 38 ohm VC.

-not sure if the Phantom speaker was always 12 inch or sometimes 15 inch like the Philharmonic.

-optional 4 unit speaker system with outboard crossover.

I just rechecked and all 3 of the amps have 2 6J5s. So i think that means they are for the 3 phantoms.

Six-tube amps with pair 6J5's are for Phantoms.

The Jones plug FM Phantom cable is a no brainer  - for the amp set with Jones socket. I think you will find the smaller cable out go the Set Jones plug go to the on/off switch.

The AM/SW Phantom with logging scale - likely the Amp with  6J5's next to the 6L6s mid chassis.

The red band Phantom, no logging scale - I would expect an amp with 6V6's, not 6L6's. Look carefully at the tube number embossed on the socket.
