125B is for sissy boys and gay people (no offense Tube Exorcist)
Do one for DEM size-E with big audio transformer and wall powered. Should have bigger headrom that way

Are you trying to tell me that the enlosure size doesn't matter?

Sounds heretic

I have a Tyco on my breadboard. I've tried 3 variations of the circuit; Mr Huge's Tycobrahe schematic, the hand drawn one and the Dunlop Octavio. No matter how I combine the dozen different types of transistors I have I don't get such a nasty and thick sound. :cry:

I've had the GGG Tyco and the wedge Dunlop octavio. I've watched a bunch of YT videos of different clones and I'm starting to believe the guys who claim that there is nothing like an original Tycobrahe.

Howdy folks, first post here. This thread is pretty old with a good bit of "link rot", but from the surviving gut shots it seems Q1 is reversed from some of the common schematics floating around the web (GGG and Fuzz Central), with emitter connected to the 220r and 220k etc. The Jeorge Tripps-drawn schematic I have backs that up.

Can anyone confirm that the original Tycobrahe transistors are MPSA18, 2x 2N6519?

Thanks!

I can confirm the q1 is MPSA18. I'm looking for pics of the others as we speak.
