Re: GEC Junior Fineline project.
Sorry I don't have a manual but I would start by checking voltages on the BF196 & BF197 transistors, no or low collector volts would suggest a supply fault. Check particularly between the base and emitter for around 0.6 - 0.7V, replace any that are wide of the mark. If the BF196s are less than 0.5V then you may have an AGC fault.
