In Reply to: How long can electrolytic capacitors (in a tube amp) last? posted by Leslie Loh on September 28, 2004 at 03:00:30:
From your description it seems quite likely that you should indeed replace the electrolytics that are "bulging" or are exuding a liquid. However, there is no way you have to spend $1080US in order to do that (12 caps), unless the amp uses Black Gates (which I doubt). The most cost effective thing to do is to determine the brand, voltage ratings and values of the bad lytics and then look to buy replacements from the various suppliers, many of whom are sponsors of the Audio Asylum. In some cases, this is an opportunity to upgrade the sound of your amp, if you should choose to improve on the quality of the lytics. Perhaps the ARC factory cost estimate includes labor as well as parts; if so, it's not so unreasonable. However, if you can do it yourself you will save a bundle. By the way also, the output tubes are not the only tubes that occasionally need to be replaced; you may want to replace your input and phase-splitter tubes also, especially if they are as old as the capacitors evidently are.
