Triple Rec tubes

[paytojt]

Can 4 of the power tubes be pulled to reduce the wattage in a Triple Rectifier like in the Duals by pulling the two center ones?

I wouldn't recommend it.

Pulling two tubes in a Dual results in the output transformer taps being doubled. If you pull two tubes in a Triple, you change the OT taps by 1/3, meaning you would have a mismatched load. If you pull 4 tubes, you change the OT load by 2/3...not advisable.
