2pcs 6R3S-1 Matched PAIR (6P3C-1) Double Tetrode USSR Tube, Svetlana, NOS Valve

Description

2pcs 6R3S-1 Matched PAIR (6P3C-1) Double Tetrode USSR Tube, Svetlana, NOS Valve
2pcs (tubes) in one lot
NOS (New Old Stock) - You buy what you see at the photo
Tested - Matched PAIR-
Svetlana Brand
All tubes are tested and have good parameters. But you can get differ tubes with other parameters,
not like at the photo.
Because I have many tubes and can not make photo of each.
So, you will get one Matched PAIR of
6R3S-1
(2pcs) with very similar parameters,
but they must not be the same as at the photo.
Hope for your understanding and have a good shopping!
