DavidR Posted October 27, 2021 Report Share Posted October 27, 2021 I don't know of any 2500uF non-polar caps being made today. You can get (2) 1000uF + 500uF or (5) 500uF. Did you want to stay with non-polar caps like ones that came with the speaker or upgrade to film caps? Film caps cost more but will always measure the same. They are also physically larger than an equivalent capacity NPE cap. (NPE = non-polar electrolytic) Attached is what I'm putting into my second pair of 9s Quote Link to comment Share on other sites More sharing options...
Rickyboy Posted November 26, 2021 Author Report Share Posted November 26, 2021 have you already tested your 9`s with the new battery of caps ?? Quote Link to comment Share on other sites More sharing options...
DavidR Posted November 26, 2021 Report Share Posted November 26, 2021 I have not. I am busy restoring another pair of AR9s that I will be selling. I'm currently sanding the cabinets for re-staining. Not my fav thing to do. I have used similar caps (i.e. Clarity CSA+ AudiCap Theta for series caps and Dayton for shunt caps) in other AR speaker rebuilds. They sound very nice and good detail.

Stimpy Posted November 29, 2021 Report Share Posted November 29, 2021 Lot's of different bypass capacitors in there @DavidR. Have you had listening sessions with each type, or just experimenting? Quote Link to comment Share on other sites More sharing options...

Have you had listening sessions with each type, or just experimenting? Just 3 types: AudioCap Theta, Cornell-Dublier 940C and Dayton film and Foil bypass caps. I have used the Thetas and C-D in my AR90s. I think the Clariy CSA and Thetas work nicely together. I have used the Dayton but not in combo with other bypass caps. I don't expect to hear any difference. Quote Link to comment Share on other sites More sharing options...
