Viking 500 J110 - Broken chassis plug

[kc2we]

The J110 center post on the (RF) chassis mounted 9 PIN female is broken on the "500";  just placed the unit on the work bench. Got it that way from the estate sale. I want to replace it (don't want to guess about pin allignment any time the inter-connecting cable is removed). The only available chassis plugs I can find on the web are black bakelite and the original was mica filled (yellow). Any reason why the black won't work here? It's only carrying control voltages - no RF. I'm tempted to replace it with an MS style 9 pin military connector set (about the same footprint) and be done so it can't be broken again. Any ideas for a source for the 9 pin "noval" plug though? I guess can be installed with a standard tube socket spring washer and the run-of-the-mill mounting plate if I find one. Suggestions welcomed.

This is a very common issue with this type of connector.  The antique radio supply stores sell a little piece that slides over the pins of the existing connector and has a new locator pin but I have never seen them for anything other than 8 pin plugs.

Several years ago I acquired a couple of Pierson KP-81 receivers and both had broken locator pins on the chassis mount 11 pin connector.  I really did not relish the idea of replacing these since the original wiring is dense in that area.  Instead I used a Dremel tool to cleanly smooth off the remains of the original pin and then used the same tool with a cutoff disc to liberate a pin from a defunct tube.  I carefully aligned the replacement pin and attached it with high strength epoxy and that worked fine.  I have since used this method to repair several connectors.

Yo'

   I run into this quite a bit. My low cost, low hassel
solution is to paint a line with red nail polish across
the Properly oriented Plug right up on to the chassis.
2  or more coats may be required as it's "Pigment
 Deficient". But fairly resilient. Not like your pulling
them too often anyway.
