I've seen HP numbers cross referenced to 2Nxxxx, but where I can't recall.
Have you tried Google? Also ask on the boatanchor group.
good luck

On a hot summer night the output of my 8640B suddenly disappeared. Later I
learned that the output amp (marked 5086-7068) had failed. Any idea where
to
get a replacement? Apart from buying a second generator off course. Any
help
will be appreciated.
