Philco Model 66 120hz hum in speaker
#15

No your choke is much smaller: 32-7018 is 70H and 2,300 Ohms.

But then #49 cap I mentioned before is a better one to increase than #50 8uF one.

Also you could serialize a resistor with the choke to bring it up to 2,300 as otherewise some of your voltages are higher, plus it will help filtering. The current is below 10mA so the dissipation is minimal and mere 1W resistor should suffice. Then the 49 cap might icrease just a tad.

Again, whatever works.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
