Hello,
my goal is to deglitch a power supply for tube electronics.
The output shows glitches, which seem to be of higher frequency than the random DC output noise.
Is there any possiblity to add or varying the circuit to avoid those glitches?
Maybe to improve the output DC in Signal-to-noise ratio, less hum, too?
The circuit draws approx 40mA of current and the voltage Uce of the darlington IC is 15V.
Another strange thing is, approx one or two minutes after power on, there is a loud humming coming from the speakers (I use it as a preamp PSU). When loudest, it become very fast quiet again, like it was before. Maybe it has something to do with the warmup time of the preamp tubes?
How to avoid this? Will tube rectification make it better?
Many thanks for your ideas.
