National NC-300 eliminate 6AL5 diode tube. Add .56uf cap to AVC line for better SSB reception
6AL5 tube pulled and signal diodes added underneath to the 6AL5 socket.
.56 capacitor added to the AVC line to ground.
Not sure this is desirable to clean up the SSB.
IT seems to AVERAGE the AVC line and does NOT provide fast attack and slow decay.
