Craig, i am unfamiliar with some acronyms.
DI  = ?   IPA = ?
I mean, i know the common meaning of IPA, but that's probly not what you meant.

Subject: [ARC5] Restoration questions...

Getting the bench set up for going thru all my SCR-269 and -274 stuff. A couple of questions for the group.....

On cleaning...Dawn dish soap and DI water in an ultrasonic bath, with a DI water and then isoproply alcohol rinse for removing all the sticky stuff and old grease and lubricants ok for racks and control heads, of is there a better process?

Dynamotors...IPA flush and warm air dry for cleaning the rotors and bearings?

Recommended lubricants for dynamotor bearings, control head gear trains and shafts? Wondering if some of the high grade watch lubricants for gear trains and pivot oils would work well for everything else?

Suggestions and/or better ideas?
