[Moon-net] For HP8640 Sig gen owners

[peter blair]

 Thanks to many who helped with the circuit.  Ive located the fault ( thats the good news!) the bad news is that its the  output amplifier ic thats blown, its a special HP in a gold colour TO3 like case with the number 0960-2081 on it . If anyone has any bright ideas on where I might find one Id be grateful. Ive done a pretty extensive search of obselete ic suppliers without sucess and I've emailed the Agilent test gear group.
 My thought is that there maybe someone who has been down this route already.
 Apologies for the BW.... but it is for EME gear testing!!
