Hello all,
I DIY a tube preamp based on a circuit from a old magazine.
It based on a 6DJ8 and 12AU7. I have some query on the power supply circuit. The circuit is attached.
Are the 2 Zener diodes (27V and 12V) in the right positions or they should be swapped?
Do you know the purpose of these 2 diodes?
regards, Ray
