After taking a long sabbatical I've gotten back to the 201 chassis. The up date is all the caps are done and resistor are check/replaced. Powered up w/o 5Z3 and the lights in the room didn't go off when the radio when on. Had 410vac either side of center of the hv winding which is good. Tubes lit as did the dial and the sm. Plugged in the mighty U7 with Homer attached to pin 1 of the 5Z3 and the chassis. This is just to see if anything catastrophic a second or so before it happens.
No big surprises. Hv went high up and drifted down to about 385V. A nice hiss was emanating from the speaker. What the heck hooked the 120' dipole to the ant post and had stations galore on BC and SW.
It's been playing for about 4hrs w/o a hiccup Took a look at the voltages on the 42's (output) 365v plt/scn -37v cg. A little more juice than the average table radio. PT is running cool.
Excellent sounding set! And that's just on the bench. I have two cabinets but neither are usable yet.
I did have a question. I'm missing the shielded wire and switch for the bass control. The parts aren't the problem but I'm not sure where wire exits the chassis. Does it come out by the dial drive? I know it connects the block by the volume control. Does the wire run under the chassis?
The Cousin been on for a bit now coming like he's in the room.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got it!
