[Moon] Multipin connectors for Siemens TWT PSU and PSU test load...

[SM2BYA, Gudmund]

Hello all,

Wonder if someone out there can help with this:

I have two NOS, 30 watt AEG TWTs for 10 GHz (courtesy of Rainer) sitting on
a shelf since nearly two years, just waiting to be powered up - but of
course no time to build a proper power supply...

However, about three months ago I managed to lay my hands on two Siemens TWT
PSUs in unknown condition. I didn't want to risk burning out the TWTs, so
started searching for a Siemens DL120 "dummy load" on eBay and eventually
found one that has now been delivered. This is not an RF dummy load but
rather a "dummy TWT" used to test the supply and all protection circuits
before connecting the real TWT.

Siemens use a 66 (11x6) position Winchester multipole connector on their
TWTs, with just ten positions actually populated. The connector on the PSU
has socket (female) inserts fitted and the TWTs (as well as the DL120) have
pins(males).

The cable connectors fitted to the AEG tubes are quite different. I would
like to replace them with Siemens/Winchester type connectors, and also make
up an extension cord to go between the PSU and the DL120. Does someone know
of a source for these Winchester connectors, and/or does someone happen to
have one or several in their junkbox (perhaps from a defunct Siemens TWT) ?
