   I have tried to work with 4 Star Electronics.  They only want to deal
   with large quantity orders.  I would be interested to hear if anyone
   has had better luck.

     [1]www.octopart.com identifies 23 of them in stock at a reseller
     called 4 Star Electronics. Bob's idea of trying a power-supply
     rectifier sounds interesting, though. Failing that, an NTE
     replacement part for AM radio tuning might work, perhaps in a
     different series/parallel combination. Just curious, what was the
     5065A acting like with the bad diode? Mine seems to run quietly for
     days at a time, but then occasionally it generates excess low-level
     random noise for a period of hours to days (see image). Every time
     I've tried to get serious about tracking the problem down, it stops
     misbehaving. Did yours look like this? It's especially annoying now
     that I finally sprung for a second 5065A, which seems to behave
     almost identically... -- john Miles Design LLC
