[NJARC] In search of an 8 inch zenith electromagnet speaker, 2150 ohms.

[Thomas Lee]

Hi John,
the speaker that the radio has is not what the schematic calls for, it's a 
model 49-166X 1000 ohm, the schmatic calls for a model 49-152, 2150 ohms. 
Should I keep the speaker and add a resistor in series once I find a 
transformer?

Thoughts?

Tom,
If this is the radio we were working on at the clinic, you DON'T NEED the 
speaker -- you need to replace the OUTPUT TRANSFORMER which is physically 
mounted on the speaker. The speaker field coil is OK (we tested that at the 
clinic), and I think we tested the voice coil and it's OK too. But check it 
to make sure.

It should be easier just to replace the transformer -- it will be much 
harder to locate a matching speaker. The primary of the output trasnformer 
tested *open* (or you've got a broken wire someplace, but I doubt it).
