I have a bunch of audio equipment that I've had sitting in their boxes since we moved a few years ago waiting for me to finally finish my basement. I'm just about there and ready to break the stuff out again. I was speaking with a speaker repair shop about having some speakers refoamed and the conversation just happened to drift to this fact. At that point the guy I was talking to said, "Oh, if you've had your amplifier and such sitting around not in use, then they are likely to fail when you power them up again due to the capacitors in them chemically deforming over time. You need to have them brought up slowly over time where we hook them up to a very low level current and slowly bring them back up to 120v over a couple of weeks to reform the capacitors." Of course this "service" was not inexpensive. I had never heard of such a thing and have spent some time searching the web to see if I could find any discussions of this. While I can find a little bit of discussion about the deforming of capacitors over time in storage, I haven't found anything about his proposed technique to bring stored audio equipment back online. I suspect if this was a serious concern, I would at least find some discussion of it. While a lot of my old equipment is somewhat obsolete now, I do at least want my power amp back in service. Did this guy see me coming and hoping for quick buck, or is there a legitimate issue here that warrants such a "service" as he proposes. Thanks.
