Hi guys!
Do not replace this schematic tube ECC88 (6922, 6DJ8) with Russian 6n1p-EV, or required some changes to the schematics?
thank you

Hi guys!
As has two tube12AX7 (ECC83) I want to use them in a tube buffer with ecc88 (Musical fidelity x10-D, view schematic), so please help about amendments to the schematics for the tube buffer to work with 12AX7.
Thank you for your cooperation and help!

the M/F is an OK thing,,, the power supply( wall wort) is your first step to improve it(big 12volt transformer) ac... its old, the power supply caps will benefit from new 105 deg type.. its realy not worth a change off valve type 6922 and family are more than up to the job
