Lot of 8 PCS!   

Note: I don’t match valves in pairs or quartets. There is no valve combination in the lot price. These valves have similar valves from European manufacturer. But be careful. Please don’t use datasheets of similar valves from the West. Valves from the USSR have their own datasheets and a correct valve test could only be done with their own datasheets (but not analog datasheets from similar valves).

 The valves can be manufactured in different years. Valve pins may be dark and have some scratches. Please remember that the valves were made 40-70 years ago. The inscriptions on the valve cylinders may be dull or half-worn.

Dear customer, you can combine shipping buying more than one lot.
