I have a couple posted here in this thread.
Hey Frazzled!
Take a look at.... www.triodedick.com (projects -> annastacia)
A dutch site, but it's a real nice amp!
Uses 7027A tubes (sellers listed on site) these are beam tetrodes, and the new ecc99 as driver/ phase-splitter.
Instead of what the schematic says, you should use 6k output transformers.
The amplifier is very good of itself but also offers a lot to tweak and play around with!. the amp is simple and promising
Mine is getting better and better, built in a new pre-amp and fitted it with tube-supply.
For pictures and the story of my 'anna' see
www.buizenforum.nl and look foor 'laatste artikelen -> een eerste project' translation: latest articles -> a first project
Hope you give 'anna'a try!!
