I recently purchased a very nice looking Crosley RFL 75 reciever. The cabinet is exceptional and I would like to get it working. I removed the chassis and was dismayed to find that one of the transformers was missing. Is there a scource for replacements?

Eric, here's the schematic: http://www.nostalgiaair.org/PagesByModel/694/M0039694.pdf

This set has two audio interstage transformers. Check the remaining one to see it either winding is open; if so, you'll need two transformers. You can use a Hammond 124A (RadioDaze Part No. HX124A, $13.26).

Also, check the grid leak resistor - probaby drifted up, in which case you can haywire a 2-meg replacement under the chassis.

Should be a nice player.

I measured the resistance of the existing transformer it has about 500 ohms on one side and 7000 on the other is this ok or should I just replace them both? ::Eric, here's the schematic: http://www.nostalgiaair.org/PagesByModel/694/M0039694.pdf

Hmmm. I assume you're measuring 500 on the primary and 7K on the secondary. Double check your readings.

I would have expected the ratio of primary:secondary to be closer to 1:3, rather than 1:14. But usually, these xfmrs either fail open or are OK. I guess there could be a poor connection to one of the secondary terminals? If this is a typical Crosley audio xfmr, you can remove the end bells, and get at where the windings connect -- for inspection.

Again, if these are typical Crosley xmfrs, with 1/2" center leg where the winding is, you can keep the iron core, etc., and just replace the winding + bobbin. They are available from either RadioDaze or AES (Hammond 124C) - would save you a couple of bucks and allow at least one xfmr to look original.

I removed the transformer from the chassis and dissasembled it. At the windings I measure 500 ohms primary and 6000 ohms secondary for a ratio of 12 to 1. The replacement transformers reccomended (Hammond 124C) are 10,000 ohms primary and 70,000 secondary for a ratio of 7 to 1. Is the actual resistance reading what is critical or the ratio? Should I order one or two transformers? It would seem to me that 7 to 1 and 12 to 1 are not that far off ont know. ::Hmmm. I assume you're measuring 500 on the primary and 7K on the secondary.

:Also I was wondering if there is anyone marketing a power supply kit for these battery radios. 5 volts for the filaments, 90 volts and 45 volts I believe?
