Qualified service technicians disappearing! Recommendations wanted

Somewhat local to you, EBC Electronics in Manville NJ.  People ship gear to him from all over the country.  He does great work at reasonable prices so he is swamped.  I have used him for SS amp output transistor replacement.  Right now he is too backed up to accept new repair orders.  If you reach out and say your local he may be able to fit you in.  

What about Audio Classics?

We work on the earliest vintage tube equipment to modern equipment with digital interfaces and surface mount technologies.

FYI:  I found this info: “The typical repair time for a McIntosh MA6900 can vary widely depending on the repair shop’s backlog and parts availability. Reports suggest it may take anywhere from a few weeks to several months. Authorized service centers often face delays due to high demand, with some users reporting waits of 4–6 weeks for parts alone. In extreme cases, delays of up to 16 months have been noted. Expedited services may be available for an additional fee at some repair shops”. 

@rluton,

I have another suggestion.  Please call McIntosh retailers, explain your situation and ask them for McIntosh repair Shop recommendations.
