Hi Everyone
Thanks for the replies. Its the mk1 plessey chassis single unit, no mains eht. Looking at this from research it should be a nice simple circuit to fix.
All valve heaters are glowing, line output glowing and you do get the line whistle noise, however I would say it does have quite a weak spark from the line output valve, certainly no strong spark, guessing I should try a new rec valve and see?
Line output capacitor restuffed all successfully! I'm just hoping the crt isn't dead
