Does anyone know how much a decent 5071a goes for these days..I hear the tube
new is about 15k..would 27K be a good price for a new unit?
I think upgrading from 5061b to 5071a might be better investment due to the high
cost of a new tube..

Fellow clock-tickers,
I have need of an HP/Symmetricom 58532A reference antenna. It
doesn't have to be in pristine shape as long as it's functional and
'reasonably' priced. For purposes of this argument, 'reasonably' means
anything significantly less than the $130 that Symmetricom wants for a
new one.
Granted, that is not an unreasonable price to pay for a
good-quality antenna, and if it comes down to it I will order one from
them. However, I feel compelled to exhaust all other possibilities
first. ;-)
Please drop me a note if you've got one available. Thanks much.

A connector on Ebay now, see: 250200168413.
Kind of pricey with no backshell or screws.

HI Mike,
I have 2 FRK's here, both use a connector made by Positronic, it's a "SGM
20".
See http://www.connectpositronic.com/downloads/pdf/C008RevC_HighDenRec.pdf
The Positronic site (for Australia) is:

I bought one complete, used connector assembly on Ebay a while ago for like
$10. The P/N on the backshell is stamped "M28748/8-D10L1A".

Bob Martinson, N1VQR

Subject: [time-nuts] Efratom M100 oscillator connector
I got a really good deal on a used Ball Efratom M-100 oscillator, and I
am unable to find a power connector for it. The manual for the unit
states that it is a part number
M28748-/8-D10LIA
Evidently the M28748 series of connectors are fairly widely used in
military equipment, but a search for that particular p/n didn't turn up
anything, none of the parts houses that I deal with handle mil type
connectors, and I really doubt of I would have any luck at all as an
electronics hobbyist calling up a defense contractor trying to buy one
connector (to say nothing of what they would want for it even if they
agreed to sell one to me...).
The connector is rectangular and has three rows of pins, seven in the
two outer rows and six in the center.
Anyone have any ideas?
Thanks in advance,
Mike

Thanks for the additional tip, Bob. Based on my post, I got hooked up
with a guy on the list that had one available.
Never the less, thanks again.
