One platinum matched pair (two matched tubes) GU50 NOS in original boxes with two (2 pcs) genuine NOS ceramic sockets. Tubes are carefully tested and matched by plate current from the huge batch we have in stock.
They are the same codes, the same year of production, from 70s, much better than later ones from late 80s and 90s.
GU50 is powerful RF pentode (Pa=40W), used in many audio amplifiers and HF linear amplifiers, very similar to Telefunken Wermacht LS50 pentode.
The ceramic sockets aren't cheap Chinese ones, they are genuine NOS Soviet production from 70s, with totally different clamp system which provides much better contact and reliability.
