I have a sweep tube amplifier, currently it has 2 6JU6 tubes in it, with 800 volts DC on the plates, the 6JU6 tubes consume 3.2 amps of heater current.
I was thinking of converting this to use 2 or 3 811 or 811a tubes, would it be reasonable to use a voltage doubler circuit to get 1600 volt from the 800 to get enogh voltage on the 811a plates, and is the heater current sufficient?
