Ballast help
 
Can anyone cross referrence Stewart Warner # 507300 Ballast resistor to a
Amperite/Claro/JFD. This is from a 1949 S-W tv # AVC-2. I have a Beitman
schematic but can't find anyone with listings for S-W ballasts.
Any help appreciated.
thanks........

I just popped the ballast out of mine and it's a
JFD "Replacement for Stewart Warner" the number's the same SW507300.
I found a new one online not too long ago, I'll try to find out where.

The Chassis is a Raytheon, I have a SW factory service book for these sets if you need any info scanned.

Found it at Play Things of the Past:

Home page: http://www.oldradioparts.com/

Ballast page: http://www.oldradioparts.com/2a2fl.txt

The only catch is there is a $20 minimum and the ballast is $12, I think I just bought a tube or something to make up the difference.

Eric, thanks a lot. I had already looked there but missed it till I re-looked
after your info. I find lots of stuff there usually. Just emailed them to verify in stock.
Much thanks for making me look closer.
I have Bietman schematic so don't think I'll need much else, but thanks for
offer [unless you want to refinish this cabinet].
