Matched Tubes

The accuracy of matching a pair no less ±95%. Matched with our HI-END tube tester L3-3.

L3-1 and L3-3 was developed in the late 50s and was named MILY-1 (small test tubes universal, model 1). It is worth noting that it was already a fundamentally different device, when compared with IL-14, and he was more accurate and much more possible to measure the parameters of tubes. In 1960 he was admitted to GOST name appliances and meter was renamed the A1-3. After upgrading the power supply it was given its present name under which it was issued before the end of the 80s.

Tube tester supplied in Europe and possibly USA. Abroad, it is known as Tube tester L3-3 and Röhrenprüfgerät L3-3 (L1-3). The device came with a manual in English / German inscription on the front panel is also sometimes translated. Illustrated description of L1-3 and L3-3 (in German). 

The initial set of cards (about 350 pieces) allows the testing of 197 types of tubes. Subsequently set modernized became more structured and expanded significantly (up to 390 pieces), but part of it was tubes excluded.
