My first venture into the realm of subminiature tubes. It features a class A output section and three stage preamp all implemented using 6021 triodes. Most interesting features are probably the switching power supply and that it fits into a small Hammond enclosure.

Second attempt to squeeze as many tubes as possible into an effect sized box. This time using a transformer based power supply, one 6021 and one 6112 triode, as well as featuring a class AB output section using 5902 pentodes.
