[Drake] Common faults

[Ron Hunsicker]

All,

I forgot to mention that a fault of the R8s involves the whole bunch of 
(a technical term) diodes in the front end.  In the vicinity of a 
transmitter, these can blow.

In a used an sickly R8 that I sent in to Drake, rather than 
trouble-shoot the blown diodes, they simply replaced them all.  I called 
and asked about this and the technician said that wholesale replacement 
was usually less expensive than finding the bad ones and replacing only 
those, so that was their procedure.

A technically astute friend offered that the diodes were a bit weak for 
the service and that was why there were wholesale failures.
