6AS6 is useful for audio ?

[aldovan]

Friends

If I connect the G3 of the 6AS6 to cathode , this pentode can work fine for audio pre-amplification ?

Thanks,

Aldovan

The spec sheet mentions this specifically: connect G3 to the cathode, and use as any other small signal pentode. Whether or not it works as a decent audio voltage amp remains to be seen.

It is a sharp cutoff pentode, so it should be possible. How linear it will be is up for grabs.

yes...connect G2 to plate and you have a triode...

Yes, I want use as triode.

You can make it into an electronic volume control if you connect G3 to a variable source of DC, like 0 to -18V or so. See the schematic below:

I believe the 6AS6 is essentially a 6AK5/EF95 with a tighter pitch on g3. That would mean that you have to be careful about grid stoppers etc. as it is happy amplifying/oscillating at UHF.

I connected 6SA6 pin2 to pin7, to substitute 6ak5/403a/403b/5654/ef95. Obviously you can get good price on 6ak5 family already but as LittleDot and Yaqin amplifiers are getting popular, some expensive 6ak5 like WE403, Mullard/Siemens EF95 are getting a bit pricy. You still get same performance out of 6AS6 at about half price tag of 6ak5 in general.
