I recently had a SOKOL RP204 in for repair - the oscillator mixer transistor had failed. Not having any Russian devices I ascertained that TR1 was Silicon PNP type & function RF. I fitted a BF423. Radio did not function - voltage readings showed that current through BF423 was too high. I added 10,000 ohms from base to ground to correct the bias. Radio then functioned perfectly. I have added a simplified circuit for this stage of the circuit in .jpg format to assist in servicing this first stage of the radio.
