Hi friends! I'm curious if anyone here happens to know the name of this connector. It's on the back of some RCA modules I recently acquired. I also have a BA-12A that also has 10 pins, but those are the beau or cinch jones type. On these the "blades" have a larger spacing, and the split down the middle leads me to believe the mating side is perpendicular, like an ELCO/EDAC type connector.

I've scoured the internet as best I can, but haven't come up with anything useful. The modules are a part of RCA's lower end "Rainbow Line" which included these preamps, a power supply, a line/summing amp, and some simple EQ modules. They use the MI-12399 9pin (octal type) input transformers (unfortunately not included in my purchase, but come up often enough. I'll also try throwing some other options onto a 9 pin plug just to have fun experimenting).

Worst case scenario - I can solder directly to these, but I thought it'd be cool to make the output transformer boxes I'm working on mate with a connector to keep things modular :)
