Hello--
In case anyone needs a replacement, I'm offering FS a NOS
(new-old-stock) "Percent Modulation" meter, HP p/n 1120-0397-1,
1 mA full-scale movement. This meter bears a corporate
calibration sticker that seals the meter's adjustment screw,
but the date-of-calibration code is not obvious.
IIRC, this meter is an exact replacement for the percentage
modulation meters used in HP's 608-C (and possibly other
608-family?) signal generators; if that's incorrect, please
let me know.
I'm asking $10.00 plus USPS postage; I honor PayPal and welcome questions.
Thanks, and 73--
