Kinda reminds me of vintage RFT EL34 tubes. These are good tubes.
BTW... one is not NOS. It has some mileage on it. Tell by blast coming out of rectangular holes on anode plate --- putting smoke-like stain onto inner glass.
Rft tubes ,sometimes Tfk marked ,sometimes Siemens.
Value depends on how they are matched (and i don't think they
are unused tubes),and how consitent they are .
I won't pay more than 50 bucks each for unmarked ,unboxed tubes
(if they test strong and well matched)
check the bulb`s top! if you find a dimple in the center there it is obviously made by RFT. the "dimple top" is typical for RFT EL34. that perfect cylindric shape of the bulb also.
