Here’s a nifty way to hold your 6sn7 tubes when soldering! When held in a vice or wedged on it’s side, simply rotate the tube to the next pin!
Not my idea by the way.

I keep the tubes horizontal, I prefer solder not run all the way to the glass and capillary action draws it in just fine.Here’s a nifty way to hold your 6sn7 tubes when soldering! When held in a vice or wedged on it’s side, simply rotate the tube to the next pin!

A nice way to hold the tube nonetheless. Many of the tubes I replace the solder on are worth $250 up so I am pretty cautious. I might take less care with Fotons.

So just how much solder is enough? Just a couple mm? I'm guessing filling the entire pin is overkillI keep the tubes horizontal, I prefer solder not run all the way to the glass and capillary action draws it in just fine.

Here is my high tech tube holder----make the base angle anything that you need!I keep the tubes horizontal, I prefer solder not run all the way to the glass and capillary action draws it in just fine.

I generally go about half to three quarter of the way in. I use small diameter solder that fits inside the pin so I can gauge how much goes in. It is rosin core of course and I have already put a drop or two of liquid rosin flux inside each pin to cleanse the metal.

Does anyone know why a NOS tube would test brand new on one triode and practically dead on the second?

I suspect it is a bad connection, resoldering could plausibly fix that.

Someone... probably @Mr Trev went on a mono listening binge - one channel only. Or could be a manufacturing defect or bad solder on the pins.

It depends upon how it was used. I have 3 Raytheon 6SN7 that are fine on one triode, and completely dead on the other triode. Not unusual at all. And yes, I have tried resoldering the pins.

I have such a dual triod - only one side works and the other side doesn’t even light up.
Is there any use for such a tube?

Hey! off the top o my head I only have 2 mono recordings. I'd put the blame on @jonathan c , he has an amp with an actual mono switch. Don't tell me that don't f--- with the space time continuum

Cheapskate 6J5 substitution?

Only as a test aid if you are troubleshooting and want to identify which channel in a stereo unit uses which section of a dual tube. Outside of that, it is a nice desk decoration. I have 3 of them.
