Mine would be my MR74 tuner and MQ101 eq both from the mid 70's. Neither get used but still can't bear to part with either one.

The three vintage pieces I still have left in working condition are my Marantz 2240B Stereo Receiver from 1976, a Technics SH 8020 EQ from 1980 and a JVC KD-85A Cassette Deck from 1978.

The oldest audio component in my system today is a Bang & Olefsun Beogram RX2 Turntable. My Klipsch KG4s are still in service in my Son's set-up. Both in service since ~1987.

Marantz 2270 receiver which I use for the tuner only

Accuphase E 202 integrated amp purchased new back in the early 70's with a pair of Infinity Quantum 2's. Speakers were sold long ago but still have the E202, need to find a company that is capable of doing a tune up on it one of these days.

Marantz 120B tuner introduced in 1974. This particular unit was modified and brought into original spec by Bill Ammons a number of years ago.

1966-69 Sony PS-1800A turntable. After a rewiring and some, wow how it plays!
