[R-390] PTO Rebuild?

[Michael Tallent]

I have a R390A with a Teledyne plate #3776 of that contract.  I have owned
it for about 12 years, it has a Cosmos PTO, a Capehart power supply and a
Teledyne IF unit.  I have removed the IF unit to replace the bad "brown
beauties" , used a spare EAC IF unit.  Works great and has original meters
with "International" name on them.

Also have a Capehart with meters and Cosmos PTO and Amelco power supply,
traded it from a friend that had it for about 20 years.
