Hi Mars - I'm not working on one now, but have done two of them. The one for which this thread was started was my Mom's and she's still enjoying playing it. Then I found one in Chicago and I did that one for myself and love playing it. But to the point, I found another one in Minneapolis and picked that up as well. I gave that to my brother to restore and he has just done some preliminary documentation. When we have a chance I will run over there and point out a few things I want him to be aware of, but otherwise he will do that one.
One thing I'll point out here is that the power transformer gets very hot in both that I did, so in both cases I installed an external bucking transformer with a switch on it to switch between full power, full power minus 8v, and full power minus 16v. I've got both set to minus 14v (106v in my case) and they play fine and the transformer doesn't get quite as hot. I printed the case for it using my 3D printer and found a way to mount it that didn't require any drilling. I'd be glad to pint one up for you if you want to do that. I wired both of mine so that the bucking transformer gets it's power from the radio's power switch so the wiring is a bit clumsy.
ThatTubeSound did a video series on restoring a 47-1230 that was somewhat helpful: https://www.youtube.com/watch?v=5vcvh0f4Dac
I have tons of pictures and documentation so let me know if you need anything. You might find this thread interesting: https://philcoradio.com/phorum/showthread.php?tid=19577
Good luck!
