Modwright PH9.0 X power source modification


Has anyone had their PH 9.0 power source modified to the tube rectification?

If so, what did it do to the sound ?

And have you tried any NOS rectifier tubes?

I installed Russian tubes-Reflector 6S45P-E / WE437 / 6C45P / EC8020  a few years ago & noticed, a sense of "authority" from the original tubes that Dan had installed.
