Fig 15
To convert to class C bias, simply unsolder inductors L37 & L33 at the long lead side at points A & B, as
seen on Fig. 15, which is the side that should be connected to the bias circuit, in this case, VR12 & VR10.
Solder the long lead side of L37 & L33 depicted at points A & B to ground. Make sure you do not
unsolder L37 & L33 from the side that is connected to the base of the transistors. Alternatively and
simpler, the inductors can be completely removed from the board and installed on the bottom/copper
side of the board as seen done with the dipped axial type inductors on Fig 13.
Fig 16, 17, 18 & 19, show basic installations with bias modification for single and dual transistor finals
and single and dual FET finals.
