McIntosh MR77 and Revox A77 tape deck. I bought both of them new in the 70's. I sent the Mac back to McIntosh about 10 years ago and had it refurbed, probably be good for another 20 years.
What’s in your system today that you also had 10 years ago?
For me, it’s only my turntable, an LP 12, though I did have a Kore installed in 2015 so it’s not quite what it was 10 years back.
