[Collins] NYC Help with 51J4?

[eugene at hertzmail.com]

Hello all,

I have a Collins 51J4 that was electrically restored and was working very well
for several months.  About 4 months ago, something went awry in the
mechanical bandswitching/bandspread where I can no longer change bands,
and when I really try to torque the bandswitch, the bandspread flies
across the band!

In any case, it is beyond my troubleshooting abilities. I was wondering
if there might be a charitable boatanchor enthusiast in the New York
City area that I could take it to for a look-see? I am hoping it is
something simple.  I would gladly drive 2+ hours in any direction. 

If all else fails, I have lined up someone to fix it, but I am hoping to
avoid shipping costs by looking locally first.

Many thanks
Eugene
