Thank you so much, dorkwad, mesch, and almarg for your help. There's a solid state Nakamichi CA-7A on ebay. It includes the spec sheet, which is hard for me to read (and understand!), but I think it says:
Input Sensitivity/Impedence
Phono MC (36 dB Gain) 40 <symbol> V/100 ohms
(30 dB Gain) 80 <symbol> V/100 ohms
(24 dB Gain ) 160 <symbol> V/100 ohms
Phono MM 2.5 mV/50 Kohms
Tuner/CD/aux/tape 150 mV/12.5 Kohms
Output level/impedence
Pre Out 2 V/1 kohms
Rec Out 150 mV/200 ohms
There's a lot more on there if you need something else.
Would this work?
Rick
