I believe the amp was moved into the radio itself sometime in 1964. I have
the amp in the speaker box in my '64 1500 (SPL310-01587), but also have a
radio from a '64 style radio console that has the amp in the radio. (Big
power transistors in the back.)
When was the change from positive to negative ground?
