Buzzing sound

[JuhyunKim]

My S.E.X. has very loud buzzing sound on left and right channel.
Right buzzing sound changes with volume but left doesn't.
Nothing changes after switching tube.
All measurements checked out good.

Can you post some build photos?  Often something like this will be from two things touching that shouldn't be.

I sent pictures to you

I did measurements again and terminal 16 measured about 1m ohm , t32 is 109 ohm t31 is 109 ohm, t30 is 108 ohm, h3 is 1525 ohm, h4 is 109 ohm, h5 is 109 ohm, h6 is 1526 ohm, and h7 is 109 ohm.

How?  I don't see them here...

None of that is particularly out of place.
