[Heathkit] WTD for repair of SB-634 a Sperry SP-333 Display

[Heinz und Hannelore Breuer]

Hello,

I need a Speery SP-333, this is a 3 digit 7-segment display which is
used for the 10 minutes timer in the SB-634. After going thru my second
SB-634 I finally found out why on this one the 10 minute timer display
is dark all the time. The evacuation glas nozzle is broken off, there is
no gas in the nixie any more.

Does somebody have one for sale, maybe from a junker? Is there any
company which mght still have these?

I am also looking for 3 pieces of the Sperry SP-352 display. This is the
larger 2 digit 7-segment display used for the clock.

Thanks for your help.
