There are several caps on the timing board and on the inverter board that seem to be grounded by soldering to the body of the capacitor. Is this necessary to replicate?

The body of any aluminum electrolytic capacitor that
I am aware of is made from aluminum. It won't solder
without special efforts.

Could you be more specific?

Well that was a giant fail.

That is not an aluminum electrolytic capacitor. That is
a very high quality capacitor, leave it alone.

Really, if you are replacing parts like that, you are doing
your scope great harm.
