Your oldest gear?

Pretty easy for me since my vintage gear is my main gear:

-  Aiwa LP-3000 linear tracking turntable

- Conrad Johnson Premier Three preamp

- Heathkit AA-1640 rebuilt by Bill Thalman, Conrad Johnson original Technical Director for 20 years at Conrad Johnson

- Dahlquist DQ28 speakers

@nhouseconsulting  bravo the Premier was and probably still is an incredible preamp… I think mine was in first production run before Harry made CJ the word…. Carry on Sir

Hafler DH-200

and even before 

Marantz 1060
