This morning, I got my 2250B back from AKer dr*audio. It only took UPS twenty-two hours to get it from his house in suburban Cleveland to mine outside Dayton.
While he had it, he recapped the power supply and preamp boards, replaced the ICs on the preamp board, replaced the relay, completely re-lamped with LEDs, replaced the vellum paper, aligned the tuner, tightened the tuner string, cleaned and lubricated the controls, and checked the DC offset and idle current.
I got the receiver home, put it in a WC-22 wood cabinet, and am using it as a tuner/preamplifier for my 510M (also thoroughly refurbished by dr*audio) through its pre-outs. I've yet to try the 2250B's amplifier, but it serves admirably in its present purpose. This is the best my stereo has sounded since joining AK two years ago.
The 2250B was rolled out at the same time as its siblings the 2275 and 2325. Legendary Audio Classics (http://www.classic-audio.com/marantz/mindex.html) has the brochure available at the right of their homepage. This model has been nominated on the internet as the best of the Marantz 22## receivers, as most of the line has by someone at one time or another.
