[ARC5] Reviving squealing "command" receivers (re-capping)

[Bob Macklin]

I make them work by just replacing all the capacitors with modern ones.

Once the unit is closed back up it does not bother me.

There really is a limit to restoring old radios. Some of it is more bother 
than it is worth. If you want a museum piece leave it alone. If you want a 
good working radio just replace them.

If you pull out the bathtubs there is a lot of room for modern capacitors. 
And some can be replaced by disk ceramics.
