Studer A80 Ultrasonic cleaning

[AudioIngenia]

I am restoring an old Studer A80. Lots of accumulated dirt.
I have purchased an ultrasonic cleaner. Thinking of washing the parts of the Studer A80 here.
What would happen to the head block?
Some experience?

I don't see any valid reason for ultrasonically cleaning the head stack..

Why would you want to do that?

I wash a lot of parts in an ultrasonic cleaner. It takes off the paint, in some cases, or the coating. And sometimes (computer) boards fail after cleaning. I take that as "It would've happened anyway".

However, I don't think I'd wash heads. They're usually not waterproof and it seems very hard to get them to dry completely. I'm also think it would change the parameters of the heads.

Most importantly, however, is what Jakob already stated: "What would be the use?"

I just want the whole block to look shiny. I can't access every corner ...
But if nobody has done it, I won't either ...

To clean the aluminum I’d use acetone, a stiff brush and a clean rag.

I tried ultrasonic cleaning a laptop keyboard , whatever solvent was used dissolved all the printed conductive tracks, it was defective already but the ultrasonic rendered it dead as a Dodo .
A selection of old tooth brushes ,qtips , bamboo skewers , small fibre and wire brushes and rubber erasers with abrasive grit of the kind used for cleaning PCB's before soldering along with solvent, where appropriate ,  is your best bet .
A vacuum cleaner and a narrow clean paint brush will shift most dust particles out of hard to reach spaces ,
yeah its time consuming and a little tedious but at least theres little or no risk of causing damage .
I spent about 100 hours mainly cleaning my Studer C37 , as well as rectifying a few electrical/electronic/physical faults and loose linkages , slow and methodical work yet gratifying in the end when your back to  factory spec or maybe even better .
Good luck with it.
