I might be able to take on some presentation work. I have to deliver a paper on what is Guinevere with 12B4 amplifier tubes. I might be able to milk that one for an hour or so...:)

I have a few issues with front end pentode/cascode properties I am trying to work out for Merlin. It is one thing to design and build, quite another in knowing exactly and in detail how it works in order to do the best tuning/tweaking!
cheers,
Douglas
