Marshall AVT20 no sound

So I exhausted the web searches with no solutions

R53 was extra crispy so I replaced it leaving it elevated
C71 got a little diss colored but test ok with ESR meter
Board is grounded
No DC load to speaker
Tube test good even swapped it with no luck
Solder joints all look good

With everything on ten I can here faint guitar through speaker, headphones and extension speaker. If I make reverb rattle that’s louder.
Faint output through CD

Any help greatly appreciated thx
