I have an FL500 for an R-4C which I would like to exchange for an FL250 if
anyone wishes to do a deal, failing that if anyone has an FL250 and an AM 6khz
filter they would like to sell me, here's hoping,

Turned on my Working T4Xb and smoke came out the bottom of the rig which I
can't see for some reason. The filimant fuse (8A pigtail lead fuse near the
3 big power resistors) is open so replaced that, then no 250 V B+ and found
R3 1K 5 watt resistor to be open. Both of these were 'effect' and not

Finals are certainly suspect. Pull both Final tubes and see what
happens to your resistance measurement.

I just got a chance to look at the T-4XB schematic. R3 is NOT a 1k 5W
resistor, at least on my schematics!
Where is this resistor in your unit? Physically and on the schematic.

Thanks. R3 in the power supply is 100 ohms, but I believe you're right.
In this case, I'd immediately suspect C4b, but that would not cause
smoke out of the transmitter.
I'm still going with a shorted 6JB6.
