Cleveland Ohio

I have vintage solid-state stereo McIntosh equipment that I bought in the late 70's. I would like to have them tested to determine whether they meet the original specifications. In the 80's I had this done at the Mac Clinics. Today, the repair shops in the Cleveland area apparently do not have the necessary equipment. The McIntosh Service Department in Binghamton NY can do it, but their backlog for out-of-warranty equipment is 15 weeks. Can anyone recommend a good technician within a 300 mile radius that has the appropriate equipment to do the job. If one exists, my bet is that he/she is mighty busy. Thank you. GK
