[R-390] Silver solder

[scott]

Is silver solder recomennded for any of the joints?

I have just re-capped the AF module.  There are so many mechanical grounds
in this set!!  What makes it worse is the fact that the chassis is aluminum.
Aluminum oxidizes and makes for poor connections.  Aluminum wiring in a
building is an electricians dream--lots of service work.  A special compound
is now required for aluminum connections.  Why should this radio be
different??  Boy it just looks like a lot of intermittent and hard to trace
problems in the making.  I am loosening all pertinent
connections....applying Deoxit....then re-tightening.  Would seem foolish
not to while each module is on the workbench getting rebuilt.
