Hey all, finally gotten back into fixing vintage computers after a bit of a hiatus. Today I replaced every electrolytic capacitor on my 1983 C64 and as something interesting, I checked the values of the old capacitors.
All the 10uF capacitors were reading between 12 and 16uF, the 2200uF capacitor was 2866uF and the 470uF ones were 500uF and 522uF.
After replacing them, the C64 is so much better. I'd get the odd brown-out before, where 50hz would come through the speakers and the display would dim, the odd crash too. All fixed now!
