EL84/6BQ5 vs EL86/6CW5

[Jay Pemberton]

What are the differences between these two tubes? I have the full data on the EL84 but haven't found the info on the EL86....thanks in advance!

EL86 / 6CW5 has same pinout but it will NOT work in a 6BQ5 circuit. It likes lower voltages - will make more output power on 250V than the 6BQ5 can at 350V.

Sounds like the EL86 is pretty close to the Svetlana SV83 then.
