Lot #2. Listing is for one vintage field coil speaker made by Clevland. This was removed from a Conn organ that was made around 1960 and the other speakers were dated 1960. By the EIA code (433638) these had to be made in a year ending in "6" so assume it is 1956.
Approx. 5 3/8" in diameter. The cone on this has a very small tear at the 11:00 position as seen in the photo. There are no other apparent rips, tears, holes, or voice coil rubbing. I have a second one of these available and will give discount if you buy both. Voice coil measured approx. 6.5 ohms on my meter. I got approx. 3.1K ohms between the red and black field coil wires, approx. 5K between the yellow and black, and approx. 2.2K between the yellow and red.
I think these were working well while in the organ but forgot to take notes before dis-assembly so not positive. After removing the amp from organ noticed that the sound coming from the two field coil speakers was poor and very low volume. I assumed this was because the coils were no longer getting any power so I tried hooking up a 1.5 volt C battery. Sound quality improved and got louder. I then tried two C batteries and sound was even better. That is all the testing I did. I believe they are working correctly but sold as-is.
