47-1230 replacement phono - matching transformer required?
#11

I got the vm-1200a as-is without whatever it came from. One of the main factor is that it fits in the record changer tray of the 47-1230 - it is currently secured in there.

The cartridge uses a double stylus and there's a twist knob to switch between the two... But I don't have any 78 rpm records to play on it.

When I was preparing the vm-1200a to be assembled in the radio, I ran tests by connecting it to a 1970s era radio/amp unit for which I can't say the model at the moment (it is in my shed that's currently snowed in, happy winter) and the volume was not overwhelmingly low, the sound very clear. It wasn't as low as what I get on the Philco.

Here is a photo of the stylus, and the cartridge with and without the stylus. 

   
   
   

I'm OK to alter the radio, but only in a manner that would make sense for the next guy who will do maintenance in there.
