6S33S - V (6C33C - В) RUSSIAN STRONG MATCHED PAIR (difference=0) TUBES
Item History & Price
PLEASE, READ CAREFULLY EVERYTHING. IT IS IMPORTANT.About Item: NEW 6S33S-V 6C33C-В, tested and STRONG MATCHED (difference = 0 %), Russian/Soviet (USSR) tubes. The letter "V" in the heading of these tubes mean "resistant to vibration".Tubes with "V" can be used in devices during movement, which is carried in cars, for instance.Warning!
Tubes are matched by electrical parameters (Ia), not by year manufacture or producer.
Va = 120 V, Rcathode = 35 Ohms, the grid is... connected to minus (land, mass).

Wehave these number of measured items in stock. Pleaseselect pair of the list and write to us. Priceis for one matched pair (2 items).
Tester L3-3, Uf = 12.6 V; Ua = 130 V; Rc = 10 Ohms.They consist of two triodes (A and B) in the same glass envelope. Cathodes, grids and plates are internally connected in parallel. The filaments are lead out separately for each triode.
