610 & 38-624 - PhilcoPhan1936 - 01-31-2016
I had a few questions I was hoping someone could answer for me.
I picked up a 1936 model 610 chassis late last year. No cabinet. Now, I think the Tombstone version had a smaller 5 1/2" speaker. There was also a "bullet" version of the 610. What size speaker did it have
I'm contemplating building a "visible" radio with this. A clear, plastic cabinet, so the internals can be seen. I often do old radio events, and thought it would be interesting for folks to be able to see the radio's internals. Since I don't currently have a "bullet" radio, I thought it would make an interesting project.
I also picked up a 38-624, 6v battery set chassis, that has been outfitted in a 37-610 cabinet.
I know the 38-624 was made in a "bullet" style and a console style. Did both have the 8" speaker
Also, I plan to eventually restore it, and also hope to find a "bullet" cabinet. What other "bullet" style cabinets besides the 38-624 would this chassis fit in? I also want to try to restore to battery operation, so my next question is: in the "bullet" style cabinet, was the battery in the cabinet, or external?
Also, what size battery should I look for as far as Amp hours?
Appreciate any help or info anyone can offer.

Hi Jeff
The 610B tombstone uses a 5 inch (not 5-1/2") P-27 speaker with 1146 ohm field coil.
The 610T "Bullet" uses an 8 inch S-14 speaker with 1140 ohm field coil.
The 38-624T uses an 8 inch KR-17 (permanent magnet) speaker. I don't have info for the 38-624 console but the 1937 version (37-624J) uses a 10-1/2 inch HR-12 (PM) speaker.
A 38-624 chassis will fit any 37-610, 37-611, 37-620, 37-623, 37-624, 37-630, 37-640, 37-641, 38-620, 38-623, 38-624 and/or 38-630 cabinet.
If you are limiting yourself to "Bullet" cabinets: 37-610T, 37-611T, 38-620T, 38-623T, 38-624T.
The 6 volt battery for the 38-624 would have been outside the cabinet.
I'll let someone else answer the amp-hours question. You will need to determine the current draw of the filaments and the B+ if the service info does not give this info (and it should).

Thanks much Ron!
Notes taken. This will be a big help in rounding up what I need for these projects. Once I round up what I need, I'll document the restorations/projects here on the Phorum.
