Sir Daniel . . . . .

Saw this earlier, and meant to come back to you, but it plummeted down so far--so quick that I had forgoten it.

I'm assuming that your Meissner radiator is still not radiating ? . . . . and I don't see you saying if it has EVER worked in bringing in stations ?

I do belive that my provided referencing . . . bottom below . . . . is for your set ?

While I'm on the schematic take note of the [RED] mark up of the previously aspects of a hot chassis model in the respect of it being transitioned to a "floating ground" type of design by the amassing and connecting of all of the negative supply buss wiring and component contacts into a shared wirng and then that buss gets connected to the actual metal chassis proper by a higher value of resistor and a shunting capacitor.

The resistor gives DC isolation but its high resitance value limits the power level able to pass thru it and any potential damaging shock level. The capacitance naturally providees DC idsolation but is additionally able to provide a nice low impedance path to ground of any signal or audio AC components.

The isolative "Resistor" in this sets case is the [RED] boxed 220k unit, while its companion "Capacitor" is the [RED] boxed .05 ufd 400VDC unit.

Back to past times, in your fuse installation withouut my referencing being at hand at that time . . . you now see the revised mark-up of the fuse installation.

If in confirmation on the schematic ,lets initially start by evaluative troubleshooting of the basic power supply functionality, along with the AF portion and also the sets speaker.

Find the 12SQ7 and its filament and its separate notation on the schematic where you see its pin 7 and 8 being at the very end of the series arranged filament string. One of those 2 pins will have 0 Vac and the other one will have ~12Vac on it.

Get a test leads, and start with the first of its 2 clip ends, connect that clip end to one lead of an .001-----.05 ufd capacitor and the free clip end goes to #7 or 8 (50/50 odds !) of the 12SQ7 lead.

Get another test lead and connect its clips from the free lead of the capacitor to the pin # 5 of the 50L6 tube.

Turn on the set and have the unit warm up and there should be an increasing level of hum coming from the speaker as the set warms up.

Thus confirming . . . the AF output stage and power supply and speaker are basically functional.

Power down and move the lead from the former pin 5 over to the 12SQ7 pin #4.

Have the volume at minimum and then power up again and after warmup, you should be able to advance the volume control gradually, but with this much higher stage gain being available , it should now
be HUMMMMMMMM City coming from that set.

If all checks out . . . . . in forthcoming phase deux . . . . we check out the IF and RF functionality aspects of the receiver . . . .

Standing by . . . . .
