A friend at work asked if I would be interested in buying a Marantz 2275 receiver that he did some work on. He has He replaced the old incandescent backlighting with new LEDs and recapped it. The only thing not working at the moment are the level gauges. He purchased a replacement set but never got around to installing them since he bought another receiver that he has made his primary listening receiver. He’s asking $600 for the receiver, replacement gauges, and an extra set of LEDs. I have brought it home and done some critical listening and the thing sounds (and looks) pretty sweet. Is $600 pretty reasonable considering that I’ll need to be responsible for the gauge replacement?
