Dissimilar triode

Tobruk · 6th April 2007, 03:20 PM

Hi,
12DW7/ECC832 contains 1/2 12AXT and 1/2 12AU7.Do you know a dissimilar triode which contains 1/2 12AT7 and 1/2 12AU7 ??
Thanks

Hi Franco,

No.

But then I wonder where would you use an ECC82 triode where you could not as well use the other ECC81 triode?

(As far as I know the tube you mention was specifically made for Dynaco. It got blastedly expensive locally, and I never liked the combination. I converted the usual circuit - input ECC83 and concertina splitter ECC82 - to a pentode input and phase splitter, e.g. ECF80, ECF82, 6U8 or such.)

Regards
