I just had a batch of circuit boards made up to fit the popular 14 pin Diheptal PMT sockets that sell on eBay for around $12. Soldering resistors directly on these sockets is a pain, as they are really designed to fit a board.
The one pictured below is made up with all 1.2 M Ohm resistors and 10 nf capacitors and it performs nicely. I have made facility to fit a trim pot between the cathode - grid and D1 if required, alternatively it can just be fitted with a 2R between the grid and D1.
If anyone is interested in some of these boards, either raw or with components soldered, just send me a PM.
