The basic circuit of the amplifier of capacity with automatic adjustment of a current of rest of a radio tube on bending around SSB - a signal.

VT1,2 - 2SJ56 (IRF9640, IRF9620, 2Ï703À)  VT3 - ÊÒ-829à   IC1,2 - mA-741  IC3 - mA-7824. Ò1 - the transformer on field-glass K10h5h4, on 5 rings in column Ì2000ÍÌ or Ê12õ4,5õ6 Ì3000ÍÌ on 4 rings in a column. Tubes from a copper thin foil, shchechki from unilateral fol'girovannogo steklotekstolita; windings wire ÌÃÒÔ-0,07.   a - 4 coils, b - 1 coil, g - 1 coil from a tube also is used as 2õ1/2 - a coil. L2,3 - 0.5 mH, a design - beskarkasnye, a coil to a coil wire ÏÝÂ-2 O=1ìì, 8 coils, O coils 10ìì. To arrange on a payment it is vzaimo-perpendicular. Ò2 - the transformer on two stuck together rings Ì2000ÍÌ Ê20õ10õ5, is executed bifiljarnoj by a line from ÌÃÒÔ-0,12 two skrutki on sm, 4 coils with tap(removal) on middle of a line, see the circuit. RL1 - 100 W, 10 Watts.
