In some cases, we are OUT OF STOCK because we are waiting for their product. Please be patient as we are doing our best to manage inventory.


Just to let you know, nothing was more satisfying than having my amp power up and work perfectly the first time! Quiet, no hums or crackles, and nice and very sweet sounding with my strat plugged in. Thanks a bunch for the kit. I'm super stoked about my TC15. Very satisfied customer!

Warren, Winnipeg, Canada (Trinity TC15 Kit)

What differentiates our kits from others is:

  • Excellent support
  • Superior part quality and fit
  • Extensive and detailed build documentation

These are high quality DIY kits using the same parts that we use on our amp builds.

We have had many first-time builder successes but we do recommend that you be familiar with high voltage tube amp construction, safety and troubleshooting and be able to read schematics, layouts and posses solder skills in order to assemble any kit.
