Philco 90 pp 47 Restoration Questions
02-08-2023, 03:23 PM
Hi All. I just powered up this Philco 90 chassis with all new capacitors and new resistors. 10 mfd 450 v electrolytics are installed, and everything seems to be correct. However I get a fairly loud 60 cycle hum that doesn't change with the volume control. Any ideas?
