John,

I found a picture of a SCR-263 atwww.fidnet.com/~seanbart/SCR-263/BC-443-A_Top.jpg*This is the cap but
with a forward facing cable connector for the drive cable.

Charlie.

Interesting. I restored a SCR-269 system in the early 80's and vaguely
remember the cap. SCR-269 Radio Compass/ADF (3 bands) and the very
similar AN/ARN-7 (4 bands, same frequency range) run from 28V DC
and115V 400 Hz AC and are recognizably from the same stable as the
SCR-263 (and the earlier MN-26). B+ is generated by a transformer/
rectifier - 5Z4? - also 48V AC for the indicator system. The SCR-269
was good performer but had endless capacitor failures. Anyplace there
was a capacitor with B+ on one side and a ground or a grid on the
other was a problem.

Current equipment is a '50s AN/ARN-6, still looks similar to the
earlier Bendix ADF's. Best of all, the ARN-6 uses +28V on the plates.
