ASR 33 buzzing

I see you didn't bother to check the clutches. You'd have found that the clutch that reset the keyboard could be released. The buzzing may also be related to your fuse blowing the supply that feeds the receiving coil may have a shorted diode or capacitor. That would both explain the fuse and the buzz.

The keyboard was definitely jammed. I pulled the carriage over to the right and noted there's a bar on the left side that a piece of metal attached to the carriage belt hits, I assume triggering something. Doesn't work.. the bar is stuck. At any rate, I put the metal piece over it and the carriage returned on its own (spring action). I then wound the motor some more and got a bell sound. After that, the keys started to work properly -- I can see the little arms (code bars?) changing as each key is pressed. Thought maybe if the keyboard was jammed that might short the motor.. but still blows out fuses. AFAIK the unit was working before it was shipped, sort of. The seller mentioned powering it up and doing a carriage return successfully before shipping. I'm inclined to think something happened during shipping.
