[Hammarlund] NOS Hammond 600 Ohm to 9 Ohm Audio Transformers

[James A. (Andy) Moorer]

This seems like a good time to remind folks of 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, R-1051 and more. These were made for the military
contractor Marsland Eng. Ltd. Don't bother to look up the Hammond number.
They haven't made them for years. Transformers are about 3" tall. They
are cylindrical with a 2" square base.

$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-390s,
boatanchors, and these transformers seem to be getting harder to find.

N.B. - this is NOT the transformer Chuck mentioned - this one is much more
modest. 1 watt max - response flat to about 8 kHz.
