Your oldest gear?

Currently, a Thorens TD126MKII I purchased while stationed in West Germany in the mid-1970s—that’s about 50 years.  Three years ago I traded in a McIntosh MC2120 power amplifier I purchased in 1980–that’s 42 years.  Also, over the past three years I upgraded my entire system that I built in the late 1980s to 1992. 

I have been blessed to hear @whart more modern system - curated JUICE !!!!!! Loved it - great visit Bill :-)

B&O 8002(1979), McIntosh MR 78(1972), McIntosh MC2205 1975, McIntosh XRT 20(1979), McIntosh MC240 1961).  All still in full service with minimal service and sounding great.

I have some old gear, but nothing in my main system is more than 3 years old. 

I took a hiatus from audio for a number of years.  When I got back into it, I upgraded everything.
