I did my first recap recently. Easier than I thought. Pretty good deal to breathe life back into classic audio components.
Gotta remember some of them are as old as we are Mark...
That's what I thought. I mean, 31 years is a long time (for my National NV-850), even if the component is not being used all that time. Caps degrade over time regardless, correct?
Electrolytics have a water based chemical composition, and the electrolyte just evaporates over time...
Hey Mark, I hope you can get it sorted, many here can help!
I'm more pissed at the lack of electronics stores in this state. The only thing that comes close is RadioShack- and you know what that means. I'm spoiled- Baltimore, Atlanta, and Pittsburgh all had nice electronics stores and I could get anything the same day, or at least with a visit to no more than two shops. Just fed up with the hassle of making parts lists, looking through web catalogs, and waiting for delivery. It's not that a recap job is all that difficult, it's just that having 4 or 5 projects on hold waiting for the stuff to arrive is a PIA. Yeah, I'm impatient...
Caps are probably the most failure prone of all electronic components. They leak, the bulge, sometimes they even pop or split open. One thing for sure is that they're not stable over any length of time. The ones I hate most are the ones with two or three different caps in an aluminum can. At least modern caps are smaller and don't present too much problem with replacing those cans with two or three individual pieces in an old amp chassis.
