arfa.daily At whites, a MFR of metal detectors 8050's were bought in bulk
stuck into an automated tester.
A bin lamp lit that you through it into. They were an un-classified very
inexpensive if 1 amp+ 200MHz part.
Your part had this tested, labeled and is a letter of the alphabet instead of
"b" plus a 2 digit number.
I have LB's of MPSA 5550's and 5123's with gold leads, having betas over 1100.
They made crappy three pole oscillators but great touch pad amps for Moog's.
