Ef86, 6H30PI and 2 EL34
I would like do a amp in push pull 25Watts, and using:

EF86 to input
6H30PI to driver
2 EL 34 to output

Is it possible?

Why not? 2X EF86, a 6h30p, and 4X EL34 neatly follow "Uncle" Ned Carlson's pattern for overhauling the Dyna ST70. Ned runs Triode Electronics (

BTW, following the Dyna ST70 model will yield about 35 WPC.

Because more tube is equal more money and in Brazil tubes are very expensive.

dynaco ST70 is very cool projet, but I have a Willkasom project run with Ef86, ECC83s and 2 EL34 and now I want replace Ecc83s with 6h30p, because I would like learn how to H30p work, its a new tube for me.
Is it possible? and I benefit with the exchange?
