The title says it all folks, I am looking for the unloved unicorn: A black on grey OPT A-24 transformer...This is what I have on my lone LA-2A build and I am planning to build a second matched one. But I will accept any of the silk screened UTC A-24 (UTC/TRW/OPT) if none of the OPT shows up. In exchange, you will get a pair of UTC O-1 with matching manufacturing number and a pair of O-17 shield. Those are nice if you are planning a stereo pair of 176/175. Thanks!
