Hi All
Anyhow, I want uses a 6C19Pi instead of the 12au7, to be able to handle a bigger load

Some questions:
1. I have temporaily set the resistor R5 =??, R6+ ??. Can anybody teach me how to measure the noise of power supply by digital volt DC/AD meter (or oscilloscope) that I have so that I can adjust the resistor to suit?

2. There is a capacitor/resistor combo (connected in series) at the output of the power supply. Is it used as a filter or to damp the oscillation? How can I calculate their suitable values?

Any advice or information is appreciated. Help mee Thanks.
How can I calculate their suitable values?

Regards,
MT
