I am in the process of ordering the VTA board for my Dynaco-70. I have a preamp so I am looking to get the low gain version. I also plan to get the Russian PIO coupling caps.
All the different caps have me a little confused though.
One picture has two different size caps in C13-16. One for C13/14 and another for C15/16, why? Another they are all the same size and blue and another they are bigger and black. what does the value change from 88uf to 334uf do? Other than change the color from blue to black.
What type of 12AU7 are people using? Is the center tube quality more important than the other two? Like matched sides for that center tube? just any old set of three?
