Lampizator Valve / Tube Rolling Review Thread

[godofwealth]

OK, folks, I need to tap into your collective wisdom. I just received a quartet of gorgeous looking NOS Western Electric 101D tubes for my Pacific. But, their pin out is not the usual one of two small and two larger pins. Do I need a converter to use them on my Pacific?

Edited: I am not familiar with that particular WE 101D. Just find out what pinout it has for the base pins. For example, let's just assume your 101D has a B4 pinout- I have no idea if it is, and from your pics, it seems your pins are different than B4..... you just buy a B4 to UX4 pin adapter. It is UX4 into the chassis for your Pacific.

I had to use this adapter with my NOS 1940's Telefunken RS242, and Visseaux TMBF1 power tubes in my Lampi GG and Pac.

pin assignment is this: if you don't see a nose on the base of the tube between anode and filament then the only thing that helps is measuring the two connections that show low resistance this are filament. This ones must placed to thicker pins in the adapter

Thanks, I ordered the adaptors you referred to. I have a call to my Amplitrex designer, will see what he says as well....
