Tub ELL80 sau ECLL 800 sau 6HU8

[Dan Morar]

Pentru un bun amic Tub ELL80 sau ECLL 800

Identical 6HU8 = ELL80

Interesat de aceste tuburi

Multumesc

 

QQE03/12 is indeed a popular substitute for ELL80, but socket connections are different and electrical parameters aren't the same.

A perfect substitute on most instances is the ECLL800.

It can be exchanged for the ELL80 with a single rewire of pin 1 at the socket or a tube adapter.

ELL80 si ECLL800 nu sunt chiar la fel ,una are o trioda in plus ,si interesant ca are g1 comuna cu una din pentode.....pinul 1 are rol diferit la cele 2......pt  diy ,no problem, sau  atunci daca este loc se poate folosi si 2 buc EL95.

 

Daca este bun QQE2/12 atunci se poate pune echivalentul rusesc  GU17 , care se gaseste si este ieftin.

The GU-17 beam-power double tetrode is used for generation of power amplification at frequencies up to 250mHz in RF equipment. Equivalent to the QQE03/12, CV2798.
