Space Heater

The Space Heater is a simple 12AX7 preamp designed to give some yummy tube warmth with a little bit of breakup in a compact package. The gainstages are set up similarly to Particle Accelerator so there is some shared DNA with the Alembic F-2B.

With the gain low you can crank the volume without it breaking up, though obviously is will push your amp HARD as it is a high output circuit. Add some gain and you can get varying levels of breakup, with a nice hairy drive when the gain is cranked.
