Thanks Don for the tip. Well, if I have to do one thing, I can do the other one tooFailing supply caps will add hum and buzzing in the output typically seen at 120 Hz and harmonics from a bridge rectifier. If you are already in there, replacing the bulk electrolytic caps is probably easy and fairly cheap insurance. Use a good name brand.
FWIWFM - Don
Here a small amplifier is tested. 4700 extra uF is added and it is measured if there is any difference. I find it interesting. It obviously got better. Mainly in the lower frequency regions.
11:00 in he shows how he did. Then various measurement results which he shows with his oscilloscope.
Edit:
Damn there seems to be something wrong with the link. I have to press it once more to get it started. . Do not know if it is the same with you? There is probably a Youtube crap rule that prevents publication.
