Transistor Radio Restoration : Roberts Radio RM40
Transistor Radio Restoration : Roberts Radio RM40
Part two of my Roberts Radio RM40 transistor radio restoration. I show the main filter capacitor change but then move onto the audio alignment stages by doing the quiescent current setup and the dynamic output balancing. Big words for setting it up to sound nice. Not a lot of solder fumes, but enough noise to wake the dead. I save you from the noise by muting the audio at the specific 1khz tone so that your ears won't ring as much as mine did.
