hi everyone,
i am writing from London, UK.
i just got a non-functioning A77 MKIV as a restoration project.
the dummy pluh is present. the machine powers up OK. but the capstan motor is not running and the end of tape lamp does not come on. when all the buttons (Play/Rec/FF/RW/Stop) pushed they engaged with no problems, the reels motors run as they should. what should i look into to start with? my first instinct tells me to poke at the motor run capacitor, but how does that cap affects the end of tape lamp?
i can confirm that the capstan motor is NOT faulty as i hook it up to my other working A77 and it spins as soon as i turn the power switch.
anybody knows why the Rec head has Green paint dot and the Playback head has RED paint dot and not the other way round?
are the Rec and Playback boards for 2-track and 4-Track the same and are interchangeable? what about the oscillator board?
thanks in advance for your input.
