Amplifiers
We custom build hand-wired tube amplifiers from 5-100 Watts.
All of our amps feature our PureTube circuits.
You will never find a transistor in a Princeton Thermionic Amp.
Attenuators
Tube amps sound best when they are cranked up, running hot.
Maybe your neighbors don’t like that volume so much?
No worries – install our Honey Hush attenuator and wail away.

Even on days when I can’t play, I always take a moment just to look at it in awe and enjoy it. Sounds & looks great!

Dude it’s so awesome! I love how gritty it sounds – it’s like early Montrose or Pat Travers.
