Hello,
I received the TT-5F1 v2020 kit with the 5E3-VPO transformer wich has a CT 6.3V
Is it better to connect it direct to the ground and delete the artificial CT (R103 and R104) to decrease the hum?
Is my layout correct?
Thanks

Hi,

please build it with the R103 and R104. This version is tested many times and known to work. After you are sure that the amp works as it should then you can start to change things if you want.

Best regards, Dirk
