1941 Philco phono jack and plug?
#1

Having just finished working on a 41-280 and a 41-285 back-to-back, and removing an 1940s after market phono jack on the 41-285, I've been staring at the phono jacks on both sets and wondering. They have three needle-small connectors, and are placed in the schematics with the center connector to ground, the left connector to the band switch, and the right connecter to #3 RF broadcast transformer.

If I made one of these IPod adapters ( http://antiqueradio.org/iPodAdaptor.htm ), and fashioned a plug to insert the two leads off an RCA jack/plug, I would need to use the grounded connector for the RCA ground, and use the band switch connector for the signal lead? I would ignore the connector that goes to the RF broadcast transformer?

Would that be correct, or am I off base?

I like the idea of the Radio Shack audio transformers being used to combine the stereo signal into mono, and I really like the idea of using the Philco phono jack instead of making changes to the radio.

So, is this about right, or has anyone done this? I guess IDEALLY, I would need one of the old Philco plugs.
