You might want to try moving the keyboard forward and away from the operating lever that
connects to it at the back right corner of the keyboard. If the keyboard is pushed too far
back on that lever it can load up the mechanism and stall it.
It will need to be re-aligned to get the keyboard working again but that will need to be
done anyway - it's pretty sensitive to movement.
You should be able to turn the mechanism by hand but it also may need to be loosened up if
it hasn't been used for a long time.
The 33 I restored blew fuses initially and I thought it had a bad start cap. Turns out the
start cap had been removed and my unit doesn't seem to need it. Once I rotated it a
few times and put grease here and there it ran ok.
If you can get it to work by turning it by hand while it's buzzing then a bad or
missing start cap may be your issue.

buzzing definitely seems to be coming from the motor. I put a
plastic
tool to the casing and could feel it vibrating. However, I can turn
it by
hand (clockwise) and see all the gears and striker mechanisms
working.
It did manage to work briefly yesterday.. it did kind of a
'reset'. But
yeah.. not today.

Given the blown fuse I'd suspect a stuck mechanism, so the
motor is stalled
and you're getting overcurrent. Try turning the
motor by hand to confirm.

I have an ASR 33 I got. When I plug it in on
Line mode there is
a
clicking in the power supply area and nothing
else. If I put
it to
Off or Local, there is a loud buzzing sound and
eventually a 2A
fuse
on the back left side of the machine blows.
It's like
something's
stuck but the noise is kind of hard to pin down.
Wondering if there's
any Model 33 experienced guys out there.
