Tech help american motors am and cb combo unit...
 

I found a very funky AMC am and CB combo unit in a thrift store. Long story
short, it works on am, but the TX is only two watts. The audio is as clear
as a bell, but only 2 watts out.

Does anyone have any ideas what is the cause??? should I replace the final
(and the predriver)

Where would I begin to look for a schematic for this old girl!!!!!!

Thanks in advance.
