[Heathkit] 8 Pin Octal Plugs and Caps?

[Wj5mh at aol.com]

Has anyone dealt with Electronics Plus in California for the 8 pin octal 
plugs?  Will they fit the old AT-1 transmitter sockets?  Sockets for VFO and 
modulator are standard 8 pin octal tube type...  (I believe the HP-23 power supply 
uses 11 pin.)  

86-CP8 8 PIN BAKELITE INLINE OCTAL PLUG WITHOUT OPTIONAL CAP COVER $6.95
78-S8 8 PIN BAKELITE INLINE OCTAL SOCKET WITHOUT OPTIONAL CAP COVER $5.50
The metal cover is an 86-3-13.$3.95

Know of any other suppliers?  I haven't found any additional on the WEB 
search.  AES has 6 pin for $$$.

I'm building a power supply to use with some 6L6 type transmitters that are 
on the drawing board, and I'd like to use these octal sockets and plugs.

Thanks,
Joe
