I present this Liverpool layout and schematic first for critique. Please let me know if you see mistakes. These both came from study of Krÿger's schematic, Liverpool photo's, Allynmey's clone photo's, and help from Allyn and Dana. I hope those I bugged with questions understand that I REALLY did try...

Dartanion, what kind of finish did you use on your chassis? Looks like it's bead-blasted.

Most amps can work within a range of bias. Ken used -30mA and said "set it and forget it." Allynmey found bias at -49mA in two of Ken's amps. Some builders have found a better sound with a bias other than -30mA. The bias is tweakable

I wish I had had a chance to see Francesca, but, alas, no Might there be some type of adhesive between the cap and chassis we can't see Francesca's filter caps are adhesed

Your energy inspires and depresses me Tim. Dan, if you could see my mesh deck chair, leaned back at 45º, my studio flat panel monitor at the edge of the desk, a Contour Shuttle with programmed buttons! About the most energy I expend is drawing a LONG line :D As far as programs go, I just start usin...
