[Techtoolslist] Need adapter pinout BK Precision 490 #33

[Kurt Mahan]

Also the 467/490 Molex connector pinout is on page 63 of this pdf --
https://bkpmedia.s3.amazonaws.com/downloads/pdf/CRT_Setup_Chart.pdf

Pages 59->61 give you the basic pin mappings for all the adapters -- 
though not the socket pictures which are why the adapter manuals are 
useful.  Some of those tube sockets are a pain to figure out the pinning.
