The problem is that I have NO idea of it's make or model. The label has a lot of licensing and patent numbers. It also says Hazeltine Corporation. The tube lineup includes-25Z5, 25A6, 76, 6K5, 6D6 and 6A7. It also has an L42B ballast. I could really use a schematic.
Unusual combination of octal and older tubes. L42B ballast was mainly used in Emerison DP332 but that's not this radio.

:I got this radio along with a nice Philco console. At first I had no idea what it was, but I figured out that it is a chair side radio and table.

Not enough info.
My theory is that it might be a radio built as part of a radio course. I saw a radio very similar on ARF. It is a Knight, (Allied Radio) B10704. But this is not the same.
It's hard to see, but on the chassis there is a plate covering a hole that might have been for a transformer. that implies to me that the chassis is generic.
Is it possible it may be a Pacific Radio Corp Model 36? That radio has a close tube lineup. It is listed in Rider's Volume 10 (1939).

I forgot to mention that it has a 6G5/6H5 tuning 'eye'.
With the same tube lineup, the schematic for the PRC radio should be close enough for repairs. Wouldn't think the tube layout would matter so much.

You're right. No problem.
I haven't cranked it up yet because I'm moving and all of my bench stuff is packed.
It's always the very thing you need that is packed away in an unmarked box.

This schematic is NOT on NostalgiaAir though.
