Goede morgen,

Hi Ruudtx, thank you for your kind respond.

I did do grounded the connection between c21 and switch (after grid triode), there was no 1.25 signal after grounded this connection.
I think, if i pull the ech4 tube there will no 1.25 signal again since it was from oscillator signal.

Regards,

Winstony
