Default Re: More Chinese AM radio kits

I have just finished building another HX 108-2 but like its predecessor it won't work. Most of the supplied ceramic caps were out of spec, so I used my own as per the circuit diagram. There were no supplied 9018H transistors, so I used 2N3904 as substitutes. Similarly I used three 2N2222s to replace the supplied 2SC945s for the audio stages. All the resistors were within spec and the IF and audio transformers tested ok for continuity. I have no idea why the radio still won't work.
