You shouldn't. You are very unlikey to be able to make such a mod work.Hello,
What should I do to replace input opamps by an unbalanced input tube buffer in the Fosi V3? How to find exactly board points to replace opamps outputs by tubes outputs? What is the V3 input impedance?
All help will be much appreciated!
Thank you guys!
If you really want to have a tube sound input to the amp, if there even is such a thing (I don't know why you would - but it takes all sorts to make a world) then use a tube based pre-amp or buffer.
