My error, that was at the anode of V3, UBC41, other side of the output coupling cap. Should be 60 volts there; but our farm mains can climb alarmingly when there is nothing on in the parlour, often over 250 volts! Its off our own pole transformer off a 5kV overhead. By the same token, it can drop to 215 sometimes, makes soldering a challenge.
