At this stage, freedom of choice, freedom of choosing your circuit and components are unlimited. As an engineer, I will take what is needed and reliable. There are many suggestion and comment on internet.
Schematic
Tube amp circuit always associate with the power tube that you want to use, Single Ended or Double Ended (Push-Pull). You may not want a schematic which is still under discussion. Pick those which have been build before. Simple is better....lol
Chassis Layout
In Tube Amp, they use large components which must be place relative near to one another. So that the connecting wires between each components are as short as possible and do not interfere with each other. Choose one that fit all your components and they should be some space for your soldering gun. Larger is better (^_^).
Major items to be positioned, it is better to know the dimension before purchase.
