I received the Philco 16 Chassis. Has a 4 prong plug on back of chassis for speaker.
No label on chassis so I don't know how to tell what rectifier tube it used. Any way I can tell which "code" version it is?

Also, what speakers could I use with this set. I'd like to try to get this large chassis playing in my workshop. It looks like it's all there although it will need a lot of work.
