[Drakelist] Filter to swap / wtb

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, 73 Max -- I am using the free version of SPAMfighter. We are a community of 6 million users

[Drakelist] T4XB No +250V AND blown Filament Fuse

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

Paul - Finals are certainly suspect. Pull both Final tubes and see what happens to your resistance measurement. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line& TR-4/C Service Supplement CDs Paul Gerhardt wrote: Turned on my Working T4Xb and smoke came out the bottom of the rig

Paul - 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. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line& TR-4/C Service Supplement CDs Paul Gerhardt w

Tim - 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. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line& TR-4/C Service
