Figure 1 shows the schematic
of the receiver. Points “1” and “2”
are heater. Point “3” is ground (minus) and point “4” is plus
of the plate voltage. The receiver works fine from 100… 250- V.
Table 1 shows data for capacitors
and resistors. Inductors of the receiver are coiled on the base
from old tubes. Figure
2 shows design of the coil. Distance between inductor
L1 and L2 shown approximately. The distance may vary when it would
be tuned on to smooth regeneration of the receiver. Table 2 shows data for the inductor. Analog the
Russian Pentode is: to firs tube is: 6J7, Z63, 6W7, EF36, EF37A. Analog for Russian
twin Triode is: 6N7GT. Also may be used: B65, ECC32, 6CC10, 6SN7GT.
Receiver built on aluminum L- shape profile. Figure 3 shows view of the receiver. Tubes and
Plug- In Inductor placed at the upper side of the receiver. Figure 4 shows inside view on to the design.
