    I was checking out this thread on going back to improve old builds and thought I'd try redoing the wiring and upgrading some components on my Champ build. At some point I had mistakenly bought a 8+8 uf 450V capacitor and I'm wondering if I can use that for the rebuild.

    Where I get stuck is on how to handle the grounding since there is only one ground lead.

    Can I use this cap? If so, what do you all recommend for the grounding scheme?

    If I can't use it for this build, what should I use it for?

    Run a jumper from the main filter cap negative lead eyelet to the negative lead eyelet of your screen and preamp cap. Run your CT straight to the first filter cap negative lead/eyelet on the board. Everything grounds to the chassis through the input jacks. Then, there is no separate chassis ground for the power amp.
