Thanks Greg
Good GOSH some of the price quotes I'm getting on these. $45, $65+ ea
The guy next door worked for Sperry Rand, he had a draws full of
stuff........gave them away in January!
About 1000 were liquidated about 3 years ago when Sperry closed its doors
after Clinton killed there contracts here in Long Island (New Hyde Park)

I may just put it up for sale here and build a LED clock with backup batt.
This clock works (flickers) the seconds display is dead, (works when you
swap the display's)
What a bummer

Need Sperry SP-352 displays or an "alternate" for my aging GC-1005 clock

Joe -

A GC-1005 clock appeared on eBay last week and I did some research, since
it
had a display problem that I passed along to the eBay seller.

As you know, the Heathkit GC-1005 clock uses the Sperry SP-352 displays.
The displays in this series are raised-cathode, planar-gas-discharge
displays.
This particular model number is 2 digit decimal with decimal. Analog
Services is a good first telephone call for the replacement part.

Analog stocks the Sperry / Beckman / Babcock plasma (neon) displays for
SIE
/ Computalog digital readout surface panels. We have the SP-736 / SP-332
and the SP-324 (digital line power module only) for the NIM modules, and
the
SP-756 / SP-352 for the older Slim Line a/k/a Thin Line panels. They also
stock the hard to find high voltage display driver integrated circuits
(chips), DD-700 / DS8880 / SN75480 / ECG2028, used with plasma displays.

Analog also has a sister company - Scarce Components - for those hard to
find discontinued or obsolete transistors, ICs or other parts
http://www.scarcecomponents.com/

Babcock Display Division still makes these displays (But they are not
cheap), UNFORTUNATELY BABCOCK CAN NOT LONGER SUPPLY THE DRIVER CHIP.

SPECIAL HANDLING INSTRUCTIONS FOR SP-352 DISPLAYS
MOS circuit components in this assembly are susceptible to damage from
static electricity and high voltage transients. A shorting pad of
conductive
foam has been installed across the interface connector. The shorting pad
should not be removed until the terminating connector is wired and ready
to
be connected to the assembly. The interface connector should always be
terminated with either the shorting pad or the terminating connector. DO
NOT
TOUCH the interface connector with fingers or tools in the absence of the
shorting pad or the terminating connector unless properly grounded. The
data
connector should not be connected or disconnected while power is applied
to
the unit.

Good luck !!
