I would like some opinions on this speaker. I bought this off eBay and it was listed as a Philco model 20 speaker, but I am not sure that is the case. The Output transformer is stamped 2766 J. I looked up 2766 J on the Philco library and it says it is for Philco Models 40,41. It also says it has a field coil of 3 ohms.
I was hoping to re-cone this speaker and use it with a Philco 21 chassis I am working on. I am thinking since the field coil is 3 ohms I can use a 3k resistor in series with it and still use this speaker.
I guess my main concern is that it seems odd to find an oddball speaker that was used in DC only sets.
I have attached some photos of the speaker.
