Hi, that one seems to good only for low voltages. The preamp uses voltages in the 200-250 volt range. We do use a pair of LR8K4 regulators on the B+. No regulation is needed on the heater DC supply as the particular rectifiers we use drop just the right amount of voltage so it can feed the tube heaters.

Good Listening
Bruce
