Is this the bias rectifier only? As there is an adjustment pot,
the silicon diode giving you more voltage doesn't much matter
as the pot would be readjusted anyway. Higher negative bias
voltage will reduce quiescent current thru the tubes anyway,
so the danger is minimal if you didn't readjust.
It will increase the heater voltage somewhat, which IIRC Scott set at
about 10.0 volts per 12.6 volt tube heater.
