Hi all,
I have a lovely set of Summits and was wondering about recap longevity. I know that this is going to vary, but want to keep my options open for the future. My Summits have worked flawlessly since I purchased back in 2007 as the 2nd owner........no cracks, pops.....nothing. Even the L-Pads, after treating with a little deoxit work like new. I also know that capacitors don't last forever. These are pushing 40-years old now and probably only a matter of time. I play every day, never really pushing them in a controlled environment.
How hard to disassemble crossover and remove board?...........Should I have the caps replaced on the original board or will a new board built for the job be the better route?.....Does anyone have any experience with the Pass-Nelson Board that is listed on Ebay/Amazon?.....will it directly fit into speaker or are their mods needed? (Pic Below)......Does anyone have any experience with the sound quality with this change?
I don't want to have to haul these heavy behemoths to a repair center.........how much is involved with the upgrade and could an electrician possibly be hired to replace for me?
I know I'm asking a lot of questions and seems funny since these speakers work fantastic as I write this.
Thanks,
Tom
