Dan & Mick Build A Couple Of Tube Amps!

March 22, 2019

This is the audio from our video here: https://youtu.be/rBV4FYCPoIY

In this episode we board the TPS charabanc and head north, following tales of a near-hermit-like being, who, in return for crossing his palm with silver, would educate us in ye olde ways of building tube amps. Or valves if you’re British.
Thusly, we crossed river and ravine before happening on the opening of a great cave, strewn with the carcasses of dead amps the souls of those who had abandoned them. Uttering the magic words, we were granted entry and following a soldering initiation test, festooned with the jewels of the hermit’s brain. Or if you’d prefer…

Chris Fantana of Rift Amps walks us through building a couple of Fender 5E3 Deluxe clones.
We then return to Schwangri-La and plug ‘em in. Simple as that!

A word on cabs and speakers. Chris has a cabinet supplier who builds and covers the cabs, so we don’t get into that in this video - it’s a step too far for a single day! The choice of tweed or Tolex is purely cosmetic - we thought we’d have one of both.
The speakers themselves are WGS G12Q. We might get into trying different things as time goes on…
