Does anyone have a source for a 182B/482B? I've tried radiodaze and Tubes and More and a few others that came up on google. I need to replace one in a Sparton Jr. that has an intermittant filament.

Thanks.

Mike M.,

You might try heating the filament pins (1 & 4) and remove the old solder and reapply fresh solder to the pins. I have found a few times in the past that some tubes I had had intermittent filaments and I found the wire from the tube filament to tube pin wasn't making good contact anymore and after resoldering the intermittent was solved.

Looking it up in the database here, it looks like a UX 171A is a substitute, for parallel filament operation only.

The '71A is a much more common tube to find.

Thanks guys. I never thought about resoldering the pins or using a 71A as a substitute.
