Hi,

Good ideas. Since I am only looking at tube amps and preamps, I agree 500
kHz or so will do. I'll look around on eBay for the HPs and other lower BW
Tek options.

There's no law that says you can't have two scopes: start with what
you can easily find, and then you'll be in a better position to know
what you need.
