Dear Pete,

No wonder the previous owner sold it!

Best,

Joe

John e-mailed me about this unit.............when he changes the I.F.
bandwidth, the pitch of the internal receiver noise does change, indicating
that everything from the I.F. strip through the audio is working. Hopefully,
it isn't that 1st mixer that is blown. It appears that the SD5400 is now
considered an obsolete item. That's the easy part. It could also be a
failure in the synthesizer that provides 1st LO injection, but that is
probably unlikely.

John also told me that the backup battery has leaked, so hopefully none of
the plated through holes on the controller board have been damaged from
corrosion.
