Philco Speaker
#1

Hi everyone,

I'm new to this phorum and new to electronics. I have a question about a Philco speaker that I have. It came from a 1934 Model 14x. I am trying to find out the specs for this speaker. Is there a place where this stuff is posted?

The information on the speaker is 32-9035G 9-3 which is printed on the field magnet coil. The Output transformer has the number 32-705 2N and there is a U-3 printed on the big iron back.

Specifically, I am trying to find out:

1. The impedance of the speaker coil.
2. The operating voltage of the electro-magnet.
3. The primary and secondary impedance of the output transformer.
4. The operating voltage and current of the output transformer.
5. The output wattage of the speaker.

I have measured the speaker coil resistance and it measures 2.3 ohms. I'm guessing that it might then have a 3 ohm impedance?

The Resistance of the Electromagnet measures 1123 ohms. Does that sound about right?

The resistance on the primary of the output transformer measures 170 ohms and the secondary measures 0.6 ohms. Does all this sound right?

Thanks for your guidance.
Daniel
