Hello Gentlemen,
Helly Wiseguy - Terry, nice to hear from you.
PS: I am the proud keeper of Terry's CT-100 right here in Paris.
For ChrisW6ATV here's are some useful documents concerning the 15GP22 20 pin Jedec connector. Data was Scanned from the C73599 RCA developmental tricolor tube (Lab 15GP22 precursor). Courtesy of Chuck A. & John Folsom Jr who obtained copies from this priceless RCA lab data.
3x already posted documents here:

see middle of page 3 of this thread.
I also "followed the trail" to Hammamatsu Photonics. No help there & no reply to several Mails sent to their sales office here in France.
Here is their worldwide site :

You might have more luck than i did.
Problem was solved thanks to the kindness of John Yurkon who sent me a base - Thank God for HUGE PMT's being used in high-energy physics research.
Hope this helps,
Best Regards
