Solder /fix a wire to point 11, when you touch it to point 9 , you should get a click in the ear piece, this tests, the last two transistors to a certain degree. Get you DVM/multi meter (on volts) and measure between Point 11 (the wire) and the junction of the 10K and 22K, feeding the first transistor, while doing this put your finger across the tuning capacitor, this should stop the first stage squegging and the current will rise so your voltage will fall. Once you have proved this the problem could be in the tuning of Vc and the coil. Try spreading the turns of the coil (12 turns air spaced about 15mm long?). Come and tell us how you got on.
