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, 2703)  VT3 - 829  IC1,2 - mA741  IC3 - mA7824  1 - the transformer on field-glass K10h5h4 on 5 rings in column 2000 or 124,56 3000 on 4 rings in a column. Tubes from a copper thin foil, shchechki from unilateral fol'girovannogo steklotekstolita, windings wire -0,07, a - 4 coils, b - 1 coil, g - 1 coil from a tube is used as 2h1/2-coil. L2,3 - 0.27mH, a design - beskarkasnye, a coil to a coil by wire -2 O 1, 6 coils, O coils 10.    To arrange on a payment it is vzaimo-perpendicular. RL1 - 51 W, 20 Watts (10 resistors MLT-2 510W.). LX - O coils (average) 80, O tubes 6 Cu, 12 coils, length of the coil 120, inductance 8,4 mH. Taps(removals), for reception of other values of inductance, - to switch zamykateljami from MANAGEMENT INFORMATION SYSTEM RPU -631.
