There's not much to it. As per ARC Upgrade Instructions, remove 4 white MIT 1.0uf caps at (C4,5) (top of PCB), and remove 4 white MIT .01uf caps at (C6,7) (bottom of PCB.) The small caps are bypass caps in parallel with the large ones. Solder in 4 .68uf/600V V-Cap TFTF in vacated positions on top of PCB. Face red lead toward input tube and green lead toward power tube. Pad the replacement cap up from the PCB with double-sided cushioning tape from Radio Shack.If you can't afford V-Caps, I suggest Sonicraft Platinum or Mundorf Silver/Gold.
