The "Digi-Key PN links" are broken on the How-To site, so I tried to find the closest ones they had:
22uF 50V: P5568-ND (mfg PN: ECA-1HHG220)
100uF 25V: P5540-ND (mfg PN: ECA-1EHG101)
47uF 50V: P5570-ND (mfg PN: ECA-1HHG470)
Have caps just gotten smaller in the past 20 years, lol??
Caps on my board are in good shape though so I'll wait to swap them.
Thanks for help!
