I've asked around on a few boards I frequent and have searched google groups
for some info on this but haven't found anything conclusive so here goes: i
bought a working B&K 466 analyzer restorer and in the absense of a cr-23
adapter I made my own from an old neckboard. Using the pinout information
provided by B&K i was able to identify all the pins on the 466 round
connector and connect them to the appropriate pins on the cr-23 adapter.
Just in case anyone wants to know it goes like this:

466 cr-23
1 9 heater
4 5 g1 grn
7 8 K red
8 6 K grn
9 11 K blu
10 1,7 g2 grn, g3, g4, g5
12 10 heater

The only problem is that because of the way the analyzer is set up, it will
only give a reading on the green. the 466 round plug has dedicated g1 red
and blue inputs that have no counterpart on the cr-23 adapter,leading me to
believe the analyzer would see the red and blue channels as open. My
question is, can i put a 3 position switch on the cr-23 adapter that would
switch the cathode (Kred, Kblu,Kgrn)being read from green to blue to red all
while leaving the analayzer setting on green? Would this activate and read
each cathode in turn or is there a relationship between the green cathode
and G1,g2 green that needs to be accounted for?

thanks!
