If your only 40 miles from NYC....why not just take it to NYC?
You'll have a better chance finding some one competent there than say...no offense... Asbury Park.
Take a drive north to Peekskill NY along the Hudson River to the Soundsmith. I have been there many times and the tour of their facility is amazing. Their website is www.sound-smith.com with detailed directions. They have worked on several of my vintage Marantz units with great results. Plus they give a one year parts/labor warranty.
