I pulled the trigger tonight and purchased a restored Marantz 2130 (https://www.ebay.com/itm/397263854940). I was looking for and found two McKay Dymeck AM tuners, the AM-5 and the DR-22, as well as the highly-regarded Fanfare. I could’ve gone any direction but was leaning towards the DR-22; however, I was drawn to the Marantz’s look with the built-in oscilloscope and average AM performance. Given the market for the 2130, I think I paid a fair price for it and comes with a warranty. Although it was a flagship component in its day and apparently is quite collectable, the McKay Dymeck and Fanfare tuners offer superior AM performance and are priced much less.
I expect to get it next week and have nowhere to put it, but at least I can update my virtual system which is now complete until I can find more money.
Thanks for all the suggestions.
