SB-101 problem

[Stu Lyon]

Wayne,
The below ad was in one of the reflectors (Heath or Boatanchors) a couple of
years ago. I bought a bunch from Brad recently and used them in the balanced
modulator of a SB-401 (which had the same problem as your SB-101) and as
detectors in a HM-102 power meter. They worked well in both applications.

You should also replace the two 220 resistors on each end of the balance
pot.
