It's a 47-1227.  

I worked on it a year ago.  It powers up but receives nothing.  I replaced all the capacitors, resistors, and electrolytics.
Still receives nothing.  Ran out of knowledge.  The antenna and ocsillator coils have continuity.

I heard somewhere that the 1st IF is known to be bad on this model. 
When I tested it, I left it wired in the chassis.  I followed the wires out of the can and tested where they were connected.  I did take out the tubes. 
I tested cans 2 and 3 the same way and got good readings. Cans 2 and 3 have continuity too.

That's where the confusion started.  How can the 1st IF have continuity but low ohms?  Could the Capacitors in the can be burnt?

The antenna coil looks like it was repaired.  The cabinet is beautiful all original.  I was thinking it was a lightning or power surge victim. It fried and put in a corner.

Rambling on.....sorry.
