Your oldest gear?

Oldest Piece:  A McIntosh 225 amp built in 1963.  Still has the original tubes.

Oldest I’ve Owned:  Kenwood KA-9100 amp and Electro Voice Interface 3 speakers, both from 1977.

For some reason, posting from flcker doesn't work. I'll post a photo later. 

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.
