1964 Sansui 1000a tube receiver. 50wpc beast completely restored 2 yrs ago. 
1978 Thorens td-125 mark ii turntable w/
sme 3009 arm and Shure v-15 cart.. 
i just love the sound of this tt. 
2 great vintage pieces I’ve had for decades. 

Koss CM1030s purchased in '81, Now delegated to bedroom
Carver Amazing Silvers, purchased used somewhere around '93
Two Carver TFM-42 Amps, purchased around '89

My two Technics SL-1700mk2 turntables that i recently restored and my Sony TC-K570 3 head cassette deck. 

I might have the record with my Harmon Kardon 930 receiver. This unit came twin powered @ 45 watts per channel and the that McIntosh traveling lab measured at .005 in 1972. I still use it as a second setup with a equally old mc 250. The hi has a preamp out.! Bought it new in 1972.
