Time to recap the 2nd KEF 105.2 (after about a year since the last one). I'll post more photos of this as I get underway. I expect to have this finished this weekend. Time to roll up my sleeves and dive in. Now...to figure out which one of these is the one I need to recap...50/50 chance, I guess. Where's my screwdriver?
Here's the capacitors and values for the KEF 105 Series 2 (105.2) speakers:
QTY PartNumber Product Price Ext. Price
4 027-328 3.3uF 100V Non-Polarized Capacitor $0.42 $1.68
4 027-336 6.8uF 100V Non-Polarized Capacitor $0.53 $2.12
4 027-340 10uF 100V Non-Polarized Capacitor $0.58 $2.32
4 027-358 80uF 100V Non-Polarized Capacitor $1.92 $7.68
8
027-362 125uF 100V Non-Polarized Capacitor $1.70 $17.00
2 027-436 Dayton DMPC-20 20uF 250V Polypropylene Capacitor $5.77 $11.54
2 027-444 Dayton DMPC-60 60uF 250V Polypropylene Capacitor $15.17 $30.34
I bought a few extras in case I broke the leads off of any while soldering. Except in the case of the 60uF at $15.17 each! Just got what I needed on those.
My speaker SNs: 1858 and 1859 so they use the first model of the crossover.

Polypropylen caps should not be replaced
ReplyDeleteElectrolytic caps lose their electrolytic liquid over the years. That is the reason they must be replaced after, say, twenty years.
Polypropylen caps are only made of plastic and metal. No electrolytic, thus no aging. no replacing.
