Do you really need to add solder to the pins? Here is another I received today NOS. Pins look secure. Precleaned (but already pretty clean as is).
As long as the pins are secure I wouldn't worry about adding solder. Only if it develops noise down the road would you need to worry about it.Do you really need to add solder to the pins? Here is another I received today NOS. Pins look secure. Precleaned (but already pretty clean as is).
I’m more worried about the pins coming off in the adapter. But these look like they were made like this.As long as the pins are secure I wouldn't worry about adding solder. Only if it develops noise down the road would you need to worry about it.
KillerThere are three types of getters with EL34 metal base and siblings. The more “common” (still rare...) type is with solid saucer getter. Next is ring getter. Then there is this one which is like a combo of the two later getters. This one has a solid ring on the inside, and a ring getter on the outside. Hopefully my pictures show them ok.

The dreaded noise is very frustrating. I've had my share of battles - especially as I have a turntable and tube preamp in the mix. Your headphones are not particularly sensitive, so they shouldn't be too noisy at all (throw something like the highly sensitive Focal Stellia at a powerful tube amp - and you'll probably get bad results).Do you use Verite Closed headphones with the Blue Halo? What tubes?
I tried my VC with the BH and the noise and hum is too much. I tried to find some quiet tubes.
CBS Hytron 5692 is supposed to be quiet but it doesn't help much.
Are 6N6P tubes better? I will try them when I get adapters.

I reserve using mine with my DAP when in the yard in the summer.I had Focal Stellia. It didn't work well even with powerful solid state amps.
I think it would be fine with my ECP T4 amplifier. It has zero background noise (like solid state) with all headphones I tried.

Today I left the amp to heat up / play some music for ~10 hours before listening.
Now almost all noise is gone ! Even on VC the background is barely audible.
I hope this trick will work with other tubes too. I am currently running metal base Sylvania 6J5G tubes and a CBS Hytron 5692.
