i feel like if you raise these values, though affecting the plates, it would filter a little more and possibly make the amp quiter. I'm curious though. Hope you get some input. As I wouldn't mind filtering a little more of my ac30.

That's what was in the originals.

I was just looking at an MG-TD, early 1950s sports-car.

Boy did those have skinny tires!

We have a Miata, a spiritual descendant, tires twice as wide (and not as high).

The Miata tires would be all-wrong on the MG.
