Its not hard to see why Crosley made a very collectible radio, a 1937 BC/SW2 set with 6A8-6U7-6Q7-6K6-5Y3, same as a GE and a Zenith I have of the same year. This set is compact with a 4" field coil speaker and 4-wire speaker plug. The only tube failing a test was the 6Q7, an original Ken-Rad/Crosley-branded ST tube I only have a metal tube replacement for. 
The wax caps all seem to be rated .02 except for two .01 and just two electrolytics. I already changed the cord, added a fuse and two Y2 caps from either side of AC to chassis ground.
It would be interesting to hear of anyone's experience as I give this a power up and try to align it. The instructions in Riders are quite interesting to align SW especially since there is a image frequency at 910 Kc from fundamental.

I have one from a fellow old radio collector. It's in nice condition, but the previous owner drilled a hole in the front panel to right of the dial.
I just looked up the schematic and I remembered that the 5Y3 was used as a half-wave rectifier.
I haven't turned it on in at least 25 years.
