Ok.
I changed the secondary of driver transformer with no change
I changed two chokes to 100ohm resistors with no change
I put 10nF in series with 10k ohm on each choke with no change
I changed first 22uF film cap to 1.5uF film cap with no change

Is it an eml20b problem? It is the same in both monoblocks
I had it with 1084 it adj regulated heater and the same with tentlabs modules.

Any idea?
No problem with end tube only
No problem with disconnected coupling cap. I even change coupling cap with no influance
Confusing....
