Yes Edward, I'm afraid that's what drew me in to this side project! Reading Morgan Jones' Building Valve Amplifiers yesterday, I realise I should learn to dial in optimal feedback values. I just don't know how to connect up a dual gang variable capacitor!
Ed D, I downloaded the Rodenhuis book some years ago and do consult it, but I still turn to the Mullard book first as it's a print copy. I'm contemplating a Maplin Millennium type project next. I have the OPTs and a huge Leak PT.
