  • Bemerkung
  • The Philco model 604C (1936) is a compact 5-tube 2-band AC/DC receiver with a unique cabinet design. An upward-facing bakelite panel with controls covers the top of the compact rectangular wooden cabinet with rounded corners, which is finished on all sides. Band coverage is BC and 6-18 MHz. The circuit uses a 1-volt bias cell in the first audio stage.

    Model 37-604C (1936-37) is similar in both cabinet and electrical design, but with updated tube types.

Hi, All:

Working on a very unique Philco 604 I paid too much for on ebay.  I was working on a recap and ran into something I didn't recognize, so downloaded the schematics and parts list for the philco 604C listed on this web site.  Turns out it is called a "1 volt bias cell".  Seriously?  There is a battery in the darn thing to bias a tube?  You gotta be kidding.  Not easy to get to either.  I wonder how often that had to be replaced?

Anyhow, does anyone have any idea for a solution to this?  Fairly sure they are not available.  I don't even know what chemistry a 1 volt cell would be.  Mercury? 

The schematic I downloaded from the Radio Museum is in PDF, but it won't let me upload it to this post, so please search the 604 C listed in the RM database.

Also, if anyone knows where I can get a 604 schematic, that would be nice.  This thing has been worked on quite a bit, and I think I might just need one.  There appear to be a few differences to the 604C schematic I am using.  Of course, there could be work-on-it-itis, as my first boss used to say.

Many thanks in advance!

Mike

Hi, All:

Working on a very unique Philco model 604 table radio.  What a strange radio design!!  One problem I have is that the dial is damaged.  I have had no luck finding one of these.  Can anyone give me any guidance as to who might have one, or be able to repair mine?

Thanks!
