Hi Mark,
Sorry things didn't go well with your vintage Marantz receiver purchase on eBay. Perhaps the seller will man-up and make things right, he should.
I still have some Marantz gear that I've had a long time. If you have any interest in a Model 5020 cassette deck, I'll give it to you. I haven't used it in years, and I'm sure I won't in the future. If I remember correctly, it drags some during play back. It could be a problem with a belt or the motor. Otherwise, it's in good condition, and I'll send you some pics if your interested.
Like Wayne, I also have a 2220B, purchased by me in Dallas, TX in 1975. It's been my backup receiver for many years and is in very good to excellent condition. Other than a couple of dial lights that need replacing, it's a great performer that never disappoints. However, I'm concerned that it doesn't get much use, and I'm not sure why I'm holding on to it. The front and rear panel are immaculate, and the vinyl woodgrain cover is nearly that good. I'm feeling pretty generous at the moment, let me know if you have any interest in it. PM's please.
My best in your vintage adventure!
