  • Problems with A15

    Re: Problems with A15

    Thanks for the advice, my DMM was in DC position. Now I got all measurements right. Heaters were 7.1V.

    The BIAS was about -21V. Huh, I had to measure it again just to be sure. You seem to notice even the smallest errors :)

    Re: Problems with A15

    I guess my problem suits fine to this topik too. I have built my A15 to the point where I need to measure the voltages from rectifier, output of the power supply board, bias control and heaters.

    Now, I managed to get the right measurements from the rectifier (365V) and the bias control (~21V). But i don't know how to measure the heater voltages and Output of the power supply board voltages.

    So please If anyone could tell me how to measure the voltages (step by step) , I would appreciate it.
