I'm finding the "how"...

...but nothing on the "why". Apparently John Curl thought there was a positive result from the late Mr. Crump's mod though.

One of my tube preamps may be regaining some lost real estate if the new, much smaller, B+ regulator works out. That will allow me to install a physically larger, hopefully better, pot or attenuator than the Alps blue I've been using for years.

The phono section needs to see 250K though, which is why I was curious if the Crump mod increased the impedance.

I'll do more searching on the subject.
