[Collins] ART-13 questions

[Dr.Gerald Johnson]

Cannon made those connectors during and probably for a few years 
following WW2. I rather doubt they are in current production. As I recall 
(and its been about 43 years since I made up cables to run an ART-13) 
the connector has an assortment of pin sizes that makes it probably 
not standard. I recall that at the Washington U (St. Louis) ARC we 
were able to go to the EE building back basement to a storage room 
and ferret out those connectors and we had a handy 24 volt 100 or 
200 amp motor generator in the attic close to the club shack that we 
used for power to run the dynamotor that we also had.

I surplus store like Fair Radio had those plugs in the past, might still 
have them but finding them may prove to be difficult these days.

If I recall correctly, the threads on those connectors were acme, not 
V.

The Radio Handbook, 11th edition, pages 437 to 441 has an article on 
the ART-13. Edited by R.L. Dawley. I have the 12 th edition in my lap 
that has some things in common with the 11th, but not that ART13 
article. I think I have the 11th in the hamshack, beginning to fall apart 
with age. It might mention the connector part numbers.

I have a few ART-13 VFO modules, much modified in some cases, the 
others I've not seen in a decade but will within the next couple weeks 
as I clear out the space they are stored in to make room for house 
building.
