Re[2]: {Chrysler 300} 300C radio

Not sure if this is 100% correct, but my experience retrieving radios from junkyards has shown that radios from 57 Chryslers most often have the single transistor audio output stage, whereas most from 1958 Chryslers had the push pull two transistor set up. I have used the 58 audio portion of the radio with the standard 57 RF/IF portion to get better audio and maintain the connectivity of the search-tune, rear speaker, and HiWay HiFi connectors of the main portion of the 57 radio.

new output transistor and added resistor 200 ohm 5 watt to correct the bias .—one end is soldered to chassis metal not collector metal .
E of new transistor goes to existing 0. 27 ohm resistor , B goes to 2 nd lead on terminal strip that is not connected to the heatsink ( C is case , makes connection when you mount it ) set bias per instruction on print
