Hi

I had a power supply issue which wiped out 2 x BFR91A and 1 x BFR96 in the
G4DDK004 LO in my 10GHz system.

I bought some replacements on ebay.  The supplied BFR91A are in a smaller
diameter package than the originals, with the lead opposite the emitter
cropped off but visible. The board did not work with these - power down
about 20dB.  I raided some old boards for replacements after which the
board worked as before.

I wonder if anyone else has experienced similar problems?
