Hi

I have an application where I am using RC servos (Airtronics 94102) in hi
temp areas 150-175 deg F.
The servos are failing (duh!). I would like to replace the servo ic's with
higher temp versions. The first problem is Airtronics uses a custom
mitsubishi ic (#M51791AL) that I cannot get. It looks like there are a couple
of transistors (I think) labeled #8561.

Does anyone know of replacement servo ic parts or a servo board schematic to
build my own servo board?

Anyone know of hi-temp servos?

The housing is machined aluminum especially for the airtronics servo, I would
like to find a way to modify the servos rather then replace.

Thanks

Jon
