1960 Heathkit Daystrom Model AA-100 Stereo Integrated Tube Amplifier Tested

  

A really nice tube amp from 1960. This has push pull 7591 output tubes (3x RCA, 1x Raytheon all 88-90% on my tester where 91% is a new reading), four 12AX7 (all GE from 1972) and two 7199 (RCA) preamp tubes and a 5AR4 (J&J) rectifier.
