The radio began work only after supplied with the kit ferrite core inductor connected to tuning capacitor was substituted with real RF choke. With original ferrite core inductor, the circuit did not enter into oscillations and therefore did not work. Also, it was found that tuning range with the supplied variable capacitor is very wide ( ~ 70-110MHz) therefore two sections of the capacitors were connected in series. Its ground pin was left unconnected. One more issue was with the trimming resistor. It was found that circuit oscillates and therefore works only when the resistance of the trimming resistor was around 2 kOhm. It was hard to set such resistance with supplied 20 Kohm resistor. Finally, the trimming resistor was substituted by 2 kOhm fixed resistor. Also, the 100pF capacitor in grid leak circuit was substituted by 1nF capacitor. The value looks too big but the audio quality with such a value was better. I received the kit without a tube socket. I notified the seller and received from him good quality socket in one month.
