sb-100 problem

[Morris Dillingham]

Are you using a meter that will read peak output?  Tune usually uses a
continuous wave for tuning at a lower power but will indicate properly on a
regular meter without the damping for voice modulation.   For example: My
MFJ tuner has a button to press for "peak" vs. "avg" indication.  I put it
in "peak" after tuning up in "avg".  Sounds like this may be your problem
which is not really a problem, just a false reading.

Hi all

I have an sb-100 with very low output in ssb but tune is full output. I
replaced all resistors on the modulator board after i found 4 of them way
off that made things worse. I have swaped tubes out of a working  sb 102 and
there was no change. I changed the balanced modulator diodes
also no change. Does anybody have any ideas about what is going on with this
thing. Its been along time since one of these has stumped me like this.
