[Racal] Is a RA 117 compatible with a RA 66 B

[pete williams]

 My  first input to the  group..... I've  just got a  RA-117 and a
RA-66 analyser.... what does one  have to  do  - if  anything - to
make a  connection ? The   manuals are  silent on  this combo. so was
it meant to happen?   I am awarer of the  addition  and  connection
that has to be made using a  RA17.
If anyone  can direct me to a DP16-22 tube  too,  I'd be pleased .

 Many thanks
