    K40-Y Coupling Caps for the ST-70 VTA Upgraded Board

    Post by BNR_1 on Thu Sep 18, 2014 3:29 pm

    I am planning on upgrading my 1960s ST70 driver board with the VTA upgraded board. For the four 0.1uF coupling caps what size of Russian K40-Y 400V caps do you recommend using? 0.10 uF or 0.22 uF?

    Thank you

    0.22uf is the recommended value
