BTW, is it possible to audition the different preamps you have? Kung di kayo maistorbo at nasa inyo pa po
Salamat,

I want to modify my existing 12au7 amp (TONO Pre-amp to be exact).
I want to focus on power supply. What I noticed, mine is running at 150V B+.
Which do you think is better 150V or running at higher rail let say ... 250V B+.
Plan to go CLCRC. If i want to control at 8ma for the B+ do I need to add R on the
last C? I want to limit the current since I have a pair of UTC A20 that I can add
in the circuit.

and if you intend to go CLCRC all the more you need to start at higher voltage....
you will need to change cathode resistors at the first stage so that the first stage plate
sits at 1/2 B+...
you can use a vairable pot to set at 1/2 B+ and then measure the resistance
and then install the next standard value fixed resistor.....
