[Hallicrafters] SX-115 Sensitivity

[Tom Elmore]

  I have an SX-115 that seems to have lost it's sensitivity on 40 through 10
meters. The 80 meter specs out about 1/2 microvolt using my service monitor
and starting at 40 meters it is around 1 microvolt, at 20 meters it is about
2 to 3 and get worse the higher up I go in frequency. I have re-peaked the
coils in the front end and mixer with very little improvement. I have also
changed out the RF amp tube in the front end and the mixer tube and get the
same results. Anyone else run into this situation ?

Thank You
