I came across a "barn find" a few days back. A McIntosh MC-7270 power amplifier from 1991. It weighs in at 82 Lbs., puts out 270 watts per channel at 8 Ohms. It was sold as a non-working unit. In 1991, it sold for $2,499 and those that are still available today, sell in the range of $3,500+. I've ordered a capacitor rebuild kit to bring it all back into the specs of new that I'll work on this winter along with new LED lights, etc. Oh, what was wrong with it? The $13.97 power cord had failed with no continuity on the hot wire. Soldered in a new power cable and the power is back on. I paid $400 for the amplifier on OfferUp and was able to pick it up locally, so no shipping. With the capacitor replacement kit, replacement LEDs, new glass panel and the cost of the amp, I'll have less than $900 invested in it when finished.
