Hello, I am trying to set a proper quiescent current values for the tranistors in the power amplifier of Russian Klopik transceiver. I purchased a kit from https://www.rv3yf.com/ and assembled the amplifier. The circuit is attached below. I was able to adjust the collector currents of VT1 and VT2 by changing the resistances R4 and R9, respectfully. However, my problem is with the VT3: the drain current is very low (microamperes range). The current changes with changing the R13; however, it does not reach the required 250mA. This is very simple circuit but I don't understand what could be wrong with it. I do measure about +12V on primary winding of T2, and the bias voltage on the gate of VT3 is changing when I change the R13. I tested the MOSFET, it seems to be OK. I even replaced it with another one - the drain current is still low. The VT3 and VT4 of the output stage are currently disconnected and I did not apply a power for the output stage (+24V ) yet, just +12V for the initial 3 stages. Is there anything that I am missing? Any advice/suggestion would be appreciated.
