    [SripBoard Design] Starving Student Millett Hybrid Vacum Tube Amp

    Hook up your voltmeter to the power and measure the voltage with the power supply connected to the amp, then slowly and carefully move your hand close to the mosfets and observe the voltage. DO NOT TOUCH ANY EXPOSED WIRES!!!

    [SripBoard Design] Starving Student Millett Hybrid Vacum Tube Amp

    Disconnect the power supply from the amp and measure the voltage at the power supply plug.

    [SripBoard Design] Starving Student Millett Hybrid Vacum Tube Amp

    ^Looking good there Pierre.   The volume knob turned out looking pretty nice, I think.   Did you get the high power supply voltage down, or is it still running about 68v or so?   I would like to see about 12v to 13v across the heaters. I'm not sure how they will last with almost...

    is your power supply rated for 110vac input or 220vac?

    Measure resistance between RCA signal input jack(the center pin) and circuit ground.

    [SripBoard Design] Starving Student Millett Hybrid Vacum Tube Amp

    Check the resistance between the input RCA jacks and ground.   68v is a bit high for your power supply. Is it 48v dc or ac?

    [SripBoard Design] Starving Student Millett Hybrid Vacum Tube Amp

    Measure between the grid and cathode for voltage.   Measure voltage between the gate and source on the mosfets.

    [SripBoard Design] Starving Student Millett Hybrid Vacum Tube Amp

    Check some voltages and compare the 2 channels.   Power down and check the resistance from input RCA jacks to the grids, and to ground. Again, compare channels.

    Yep, wire according to the diagram you posted earlier, while looking at the bottom of the socket.

    [SripBoard Design] Starving Student Millett Hybrid Vacum Tube Amp

    Nikongod is right. The sockets should be wired looking at the bottom of the tube. They are backwards.
