Factory service manual for the 3TMR

The Motorola 3TMR is the AM radio used in 1963, 1964 AMC/Rambler Classics and Ambassadors. The cheapskates, it's got only five transistors, one more than the cheapest pocket radio, a 2N176 that drives the loudspeaker. The schematic shows AVC, but I can't hear it! Poor selectivity! Drift! Ahh... I love my 3TMR! (Really.)
