[Heath] Alignment of Heathkit SB-313 T-Notch

[Peter Brickey]

Hi,
  I am in the final stage of aligning a SB-313 receiver and cannot seem to
get
any where with the alignment of the T-Notch filter.  I can get the two
peaks at 7.5MHz  about 5kHz apart, but when adjusting C303 I do not get any
volume change on the lower frequency peak.
  I pulled out the T-Notch assembly and checked it for wiring errors and
found none.  All of the components check out Ok.

  Any ideas?

    Peter
