I need a single SP-352 Panaplex display pull or a SP-353
Really dont want to part with this clock, I tweaked up the high supply 30
volts by lowering the supply series resistor and the digits seem to be
working fine for almost 2 weeks now
Id be happy to pay for a pull, I just need a single display to get the
seconds rolling, the original one is dead
Anything, even an SP-353 (3 digit)

What a bummer, out of all the junk in the house this is what I liked
At this point I'd have to go $50 a pop or play Ebay games for parts units.
Im putting it up for sale $30, also have a Heath HM-15 SWR meter some
ninny
drilled 2 holes for mounting under a shelf $25 (email me for photos)
Scopes and stuff here http://members.bellatlantic.net/~vze2pdtg/home.htm
Thanks for all your help

Joe -
Tough choices. The displays do have a specific usage life (50%
brightness
considered time to replace)
If you restored now, would be a collectors item (see the number of Nixie
tube clocks being built). I really like these displays (warmer than
LEDs
and not like Nixies) and at least Babcock is still manufacturing the
display. I do not know what Heathkit used in the 9180s for a driver
chip
(if they used the Sperry driver chip).
Your neighbor could have been a millionaire by now.

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.
http://www.logwell.com/capabilities/stock/displays.html
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 !!
