Matt,
Been in there a few times. I went to Chippewa Valley Technical College back in 83-84 for electronic servicing. Another neat place is Indianhead Electronics downtown on Barstow, thats the place in the old church. I called them today and they still had a new SAM’s folder for my TV.
Unfortunately both of these places threw out a lot of their old TV parts years ago. Sam at Indianhead told me they had a big dumpster filled with NOS CRT's.
