HarryO Posted August 16, 2008 Share Posted August 16, 2008 A little help needed here. I picked up 3 pairs of Large AR speakers at a local auction wednesday morning. These include the AR9, AR9LSI, and AR90. (I also bought about 150 pieces of new, used, and NOS ES Sony Hi-Fi gear. Amps, pre, tuners, TTs, etc.) These came out of an estate of the owner of a Sony Retail Store and the deceased had purchased all new drivers for all these speakers. I noticed when replacing drivers and doing a couple of refoams that the capacitors on the AR90's are 350 uF, 80uF, and a couple of "normal" sizes. Does anyone know of a quality capacitor that won't break my wallet in restoring these old beauties? My normal contacts are very expensive and I'm not sure about computer grade caps for these.

Deang Posted August 16, 2008 Share Posted August 16, 2008 Harry, I imagine they are electrolytics? When you get into those sizes you're better off just staying with electrolytics -- polyester/mylar and polypropylene caps are just going to take up too much room to be of practical use. Partsexpress has a nice selection of electrolytics for speakers, I would probably use those. BTW, you can bypass them with a small value film type which smooths and opens up the sound a bit in the HF sections, but I wouldn't bother unless they are in series with the tweeter or midrange driver.
