Classic Pro Power Amplifier DCP800 This is a junk item (defective product) for sale. I recently purchased this on Mercari with the following description: "I was using this until about a year ago, and have been storing it since then. Since I am unable to confirm its current condition, I am selling it as [junk]. Please be aware of this beforehand." However, when I input an audio signal, the level meters did not light up at all, and there was no output. The seller's profile stated that they would sincerely respond to any issues with the transaction, so I expected them to cancel the transaction. However, despite their polite language, their response was completely insincere, which was a bit disappointing. It's common for playback devices and recorders to fail after being stored for a while, but it's rare for power amplifiers (I've been using Yahoo! Auctions for over 25 years and have never had this happen). I suspect that the seller knew it didn't work and still listed it (I wouldn't want to be that kind of seller). If I opened it up and checked for burnt-out power transistors or capacitors, it would be clear that it wasn't a stored item that used to work, but I decided to list it without doing anything. This is a listing for the main unit only, with no accessories. It is a defective product.
