This seems like a good time to mention the following:

I have a crate of NOS Hammond 39921 transformers with 600 ohm
primary. The secondary has 6 taps. One at 9 ohms. There are taps at a bit
over 4 and a bit over 2 ohms, plus some others. Works great for R-390
series, SP-600, CA-88 and others. These were made for the military
contractor Marsland Eng. Ltd. They are small sealed units about 3"
tall with a 2"x2" base. One of them had a date of 1963 on it.

$15 plus shipping, which is generally about $5. Breaks for 3 or more.

Apologies for the blatantly commercial email, but it does relate to 
R-390 and other mil. radios and these transformers seem to be getting 
harder to find.

Contact me off-list if interested.
