With my
Motorola 12K2 project and it's oh so similar TS-53 chassis fresh on my mind, I decided to try firing it up.
I removed the 16KP4 and put it out of harms way.
I first tried powering it up with no speaker field coil so no B+ for the set. The tube filaments lit up just fine
I'm missing the original FC speaker for this set so I'm going to use a power resistor. I measured the FC resistance in my 12K2 speaker and got 90 ohms.
I went with a 120 ohm power resistor for a little safety margin. I also used an 8 ohm PM speaker.
That got me a nice raster, but so sound or video. All the tubes were pulled from a working set set I'm pretty sure they're OK.
I noticed that the previous owner hadn't replaced a single resistor and a few old caps remain so I'll start checking & replacing those.
Here it is with an 8XP4. At least the HV is nice and strong.
