I too have a very slight hum from my super cheap valve pre amp, and this has inspired me to plan a visit to Maplins later this afternoon, so I'll cetainly be trying out the circuit. Funnily enough I know the ESP website quite well having built a couple of Rod Elliott's amps, but had not stumbled accross that particular article before - it looks pretty good.
