I love the old school discrete components. When I started in electronics, you could find vacuum tubes, discrete transistors, and IC's all in one device. I kind of miss that era.
I call those "ball game radios" because years ago people would bring small transistor radios to the game to listen to the play by play as they watched live.
Old germanium transistors have lower voltage drop fully opened than equally specified and equally old silicone ones and germaniums also required less static bias (same current but over less bias voltage from equal supply) thus less static current consumption, so to squeeze out more power and convert less of it into heat, especially in battery powered equipment it was a common practice to use them in low power output stages. Soviets used to do this in portable radios even in the 80s.
I am glad there are people like you that restore old radios and other electronics. I would be doing the same thing if I had the knowledge and equipment. I am learning some, but not yet been able to practice on anything.
I have a transistor radio that my grandmother had when she was young, and it has similar symptoms to yours. Now not only do I have motivation to go get it working, but also the information on what I should do. thank you!
Look extremely close to my little JULIETTE FPR-1250, but the 9-volt battery clip goes to a holder for 4 βAAβ batteries. The front styling is just a little different, but purely cosmetic. π»π
