For sale is one of the finest examples of a McIntosh MA230 tube integrated amp available on the market today with original McIntosh tubes. The front faceplate was replaced by an authorized McIntosh service center about 4 years ago and it is still nearly flawless. I recently had it "tuned up" to ensure this beauty functions and looks like a 55 year old gem should. Conservatively rated an 8/10 because of a few tiny nicks here and there (not on the faceplate). For it's age, it is truly incredible.  I have the original manual and sales brochure which are also in incredible condition including the schematic. Aside from a small smudge on the front cover, this paperwork looks like it was just opened for the first time. The paperwork alone would fetch $300-500.
I would very much prefer local pickup in the Northern New Jersey area. I am happy to demo it at my house, or perhaps bring it to you for a demo within a reasonable distance from 07003.
If you absolutely insist that I ship it to you, I will require you to pay an additional $450 for a proper original L-12 walnut case and brackets to be purchased from a former long-time McIntosh employee who still has these in his own inventory. This will also delay shipping by a week or so. I will absolutely not ship without the walnut case. Cost of shipping will vary but will cost at least $100 due to insurance and bulletproof packing materials. 
Cash only for local pickup. Paypal adds 3.2% if I have to ship it.
