ECC33

[M Gregg]

Just a quick question,

Does anyone know how close is the ECC33 to the 6SN7?

Same base, less heater current, slightly higher impedance, about 50% more gain.

Lower operating plate voltage ratings (300Vmax) than the 6SN7GTA/GTB as well.

The ECC83 and 6SN7 valves are completely different in just about every way you can think of except the fact they are both twin triodes. IMHO the ECC83 is nowhere near close to the 6SN7.

Along the same lines,
how does the 7N7 compare to the 6SN7? I've been going under the assumption that only the pin layout & Philco type tube lock socket is different.

Yes -but what has the ECC83 got to do with the ECC33?

A good question Indeed.

Absolutely nothing. All I can plead is that my 60 year old eye/brain combination is not as good as it used to be!

That said, there's not much common ground between the ECC33 and the 6SN7. The former was designed for use in computers and the latter for audio use. Check out the info at the Valve Museum:

6SN7GT @ The National Valve Museum
