I will use both systems of the ECC82 in parallel. Than the circuit is equal to eleven (!) ECC82 in parallel. Each triode system of the ECC82 has about 5mA at 250- 300V so long live is guaranteed. This will give 5W or a bit more. Enough for a triode amp. The power dissipation will be about 25W. Next week I'll make some nice output transformers for this triode multipler arrangement.
Hi adibrook, only 20% from the dissipated power comes to the speaker. So a triode is not an economic way to get a lot of power.
