Here we have a

Rare Western Electric 261A 261-A Brass Base Audio Amplifier Vacuum Tube ( Has Continuity )

Tested for continuity and it has on the pins diagonally across from each other for the Filament. ( As you look in the tube you can see which two pins have the filament... Continuity ok.

Please see pictures for cosmetic condition

This was in my fathers store, which I ended up with all the stock too. He repaired military Radios , Ham Radio, and sold new and used Electronic equipment of all sorts of description.

It has been in storage for years and , I am sure you will agree, it is in excellent cosmetic condition.

I do not have the facility to test it further  , though my father never kept anything that did not work.

But because I cannot fully test it myself , I have to sell it AS IS with NO RETURNS.

Thank you for looking
