Thanks! I can see now you pointed it out there's a list of transistors and diodes in red under the circuit diagram, missed it before. I'll remove and check the output transistors, I've already replaced the failed C806 and oiled / exercised the stuck tuning capacitor. I also replaced the selenium bridge rectifier with a silicon one, not sure if this causes problems elsewhere though (due to lower voltage drop).

Regards,
John
