well yeah i know pete, but as they say a little knowledge can be a dangerous thing. in the process of doing this ive read as much as i can find about audio caps. and ill tell you, opinions seem to abound! i came to notice that they varied so much they were sometimes in conflict. one fella said that filter caps of '69 era were inferior to ANYTHING made today and therefor any thing new was better than oem! another suggested that they should be low leakage with high ripple. mark the fixer said that oem caps were made to -20% and +80% which means that my 2200 mfd cap could be usable in '69 at 3960 mfd!. and so the more i read the less i knew. to make matters worse the concept's of low esr and high ripple became meaningless as what do they mean by "low" and"high"?? what numbers am i looking for? and then finally as the tolerance for modern caps is much tighter,what is the "BEST" microfarad cap for this set? i was much happier before i investigated this ill tell you.i even have one of those on your link.its a epcos b41456-b9228-m. its rated at 12000 hrs,esr 80m0hms,and 13a of ripple. in the end i chickened out and decided i'd ask here. confusion reigns supreme! i know this set is old,it was made when i was just out of high school but im determined to do the best job i can
