The more I dig, the more bodgery shows up, these are the problems as far as I can tell.
C1 is missing, R4 & R4a go to different points, and not only that, they have each had a capacitor added to them,
why has the 50uf electrolytic been fitted, EC1 and EC2 are on opposite sides, and they are both 8uf + 8uf cans, EC2 should be a 25+4+16,
and an extra component has been added from pin 5 of the output valve to chassis, It also has an electrolytic added to the speaker, connected between the speaker frame, and the white wire which comes down to pin 4 on the output valve.
Any suggestions as to what the best route to take, the output valve and rectifier have not been substituted, they are original.
