Help understanding a 89 radio rebuild new guy
#6

Gee! That is a great help, I can now see what I am looking for and it's crisp and clear and matches exactly the radio I am working on.
  Next week I get a package of more capacitors so I can continue with recapping.
  The thing I am curious about is that all but one of capacitor blocks was untouched with original soldering on there terminals.  The one that had obviously been charged was in the RF section.  I have replaced all caps involving tuning of the coils then did an alignment.
  The radio looks an molested throughout the whole radio section but around the power supply and audio is a different story.  For one thing there are at least 4 electrolytic caps at values from 10 to 30uf the original pair or 8uf caps are still there but have been clipped.  Underneath is a  home made resistance bridge of 4 dog bone resisters that are just suspended through creative, artistic soldering.   It's a mess but for now I am leaving it alone because there is quality DC and the audio is quiet strong.  I have two 8uf cans coming and then will make a project of putting the power supply back to the way it used to be.
  Do you know what voltage is expected at the grip cap of 36 mixer? I have about -1v seems low?
Thanks again for the cool factory data, Bruce
