Test Bed

I'm setting up a test/development environment to make it easier to experiment as I figure out what I want my circuit to be. It's a generic and configurable space where I can easily modify circuit pathways, components and configuration, without soldering and unsoldering connections, which are instead made across terminal strips, screwing and unscrewing wires and parts. 


(figuring out what should go where on the board...)



(Setting up power supply, tube sockets, cap cans)



(heaters on the tube sockets are wired up and working!)




Turns out, the output transformer I already have won't work well for a single ended (SE) design - the one I have is meant for a push-pull (class AB) amp, which has different requirements than SE, so I've got a pair of transformers on order:
