Hello again !
I did go through again all of the components, capacitors and again a full on voltage readings.
I also put one new old stock 6v6GT in.
Sadly there is still a massive mains hum in there and some blue light appears on the 6v6 tube. Attached some pictures of all the tubes in place.
...anything I tap on this player, the side the top, all the tubes if I tap them I can hear it in the speaker and in the headphone. Just like a massive microphonic effect.. If I switch on the motor, I can hear the motor noise also in the headphone and the speaker too.
What could be wrong here? this hum is really loud and disturbing.
and now as soon as I switch it on, a fast popping sound is heard in a fast repetitive pattern and slowing down ...on the top of that massive hum
.... and now is squealing like crazy when I turn the volume up !
