Found a 1980s CRT TV in a basement last week, the difference after recapping the power supply was night and day

The picture went from wavy and dim to rock solid and bright just by swapping out a dozen electrolytic caps that had all drifted way out of spec after 40 years, anyone else still running into old gear with cap issues?

Ha, my soldering iron skills are way worse than my capacitor spotting skills!

Yeah @lisaf38, that dry glue smell always gives the bad caps away first.

@lisaf38 the smell thing is real but honestly most people miss when caps are bulging on the bottom instead of the top. Flip the board over and check the rubber plugs.
