Looking for a schematic for an 8-transistor Magnavox AM-81 radio. Apparently it is also
found in the SAMS TSM-58 PhotoFact folder. Thanks for any help.

You mean Sams Photofact TSM book # 58? (TSM = Transistor Service Manual )
pages 69-73

I haven't used my printer as a scanner but once I scan them I'll figure out the rest as its wireless.
Not going to promise anything though. It's IF and When I have Time.

Some Resistor replacement notes, if changing-out TR4 or TR5

Say, thanks Greg! I do appreciate your posting the service note for the AM-81. I Just got it working tonight. I don't do very much transistor stuff but I can say in all honesty that I have never seen a multi-value can capacitor THAT SMALL! Argh! I removed it and replaced it with a Rube Goldberg 3-cap tangled gnarl but at least it's got some fresh aluminum oxide working in it now. Tomorrow night I will attack that service bulletin. Thanks again for sharing it.
