Qualified service technicians disappearing! Recommendations wanted

One year backlog???  Good grief!  I'm going to panic every time I turn on my MC-225 which was produced in 1963.

My advice is the same as @ghdprentice.  If I were you, I'd spend less than $1,000 for this incredible Reisong 300b Integrated Amp to use while you are waiting on your McIntosh to be repaired.

Or, spend about half that amount  on the Reisong A10 EL34 Integrated Amp.

Both would be worth keeping for another system when you get your McIntosh back.  I am amazed at how good the Reisong's perform and their build quality.  I saw a Steve Guttenberg review on them in the past and took a gamble.  Glad I did.

Another vote for AudioClassics

Audio Classics.   I would hand deliver seeing you are in CT

It kind of negates efforts to buy "made in USA" if it's no more easily repaired than that.

We are in New Jersey and also have a sound room to come hear new things.  We have been repairing modifying upgrading rebuilding for 25+ years.  We also have our own line of products.

We usually have evening hours after 7pm and weekend hours for people who work.

It is all about hearing new things, and having fun meeting new people.

I cannot offer details to reach us but if you search the forums, you can find us.

Happy Listening.
