Oh, rather interesting. I used 47uF caps of circa 1 ohm ESR and have had no real issues except skips / jumps etc on discs which are damaged, although I admit both CD160s are more "sensitive" to poorer discs than my Micromega stage 3. I have bough two 33uF, 40V BC axials which were NOS but late '82 so circa 37 years old. I have reformed them and they now measure circa 38-40uF, 0.5 ESR and have about 1-2µA leakage current (they "loose" about 1V in 30secs by self discharge i.e. only 10 megaohm voltmeter connected across them). What do you think, try them or leave the others in place as I suspect that the much newer 47uFs will not be that much different in value?
Cheers,
