ASR 33 buzzing

Fri Oct 14 01:16:41 CDT 2016

ok !   there are a set on ebay also  but  not   cheap if  you can live  
with the electronic  stuff and  occasionally print a page you will do fine with 
the links...
I like to have hard copies of  manuals   here in the  museum's library  and 
 while I like searching things  electronically  I really appreciate  
something that is  bound  paper  to sit and an arm chair and  read....
now If I am gonna  take the paper to the  greasy machine to  work, I make a 
copy of page needed  or  print  from the  online  one!    Ed#

did  you  get the  links  we  sent you   over on the greenkeys  list  for  
sources on 33 manuals and  paperwork we  sent you?  We did not get an 
acknowledgment.   thanks  Ed#  _www.smecc.org_ (

The  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.
