That looks great Darkrain, did you make the enclosure yourself or did you have it made commercially?, also, what's it sounding like?... :thumbsup

DrNomis, all the project was made from scratch, everything was modeled in SolidWorks (every nut and bolt :) ). The enclosure is laser cut and bend (made from 2mm Aluminium sheet / powder coated)

And is sounds like this (just a small demo):


Any opinion is welcomed :D

Gabriel

Sounds nice, like a cross between a Marshall and a Soldano, I like how you can switch between low and hi-gain modes, if you connect the pedal up to an amp set for a clean sound you effectively have a three channel amp....... :thumbsup

Finally i can consider the GTFO project closed. No alterations will be made (by me at least) and no further development will be done (again by me).
The project is ready to be shared and i give you a small preview of this. It's using a 1590C type enclosure, tubes are hosted inside (first version / prototype had the tubes outside).
It's using a SMPS for the HV and it requires a single 12V DC @ 800mA PSU (center negative)
If you don't remember about this project (from the DIYSB forum), here it is how it sounds:

All the project details will be posted in a PDF document (as they were on the previous version) and also a preorder for PCBs can be made at the following address: http://oseq.org/pre-order/
Please be advise that for the project you will need both main board and SMPS board (if you are using another PSU for the HV then you will need only the main board).
Soon kits will be available that will include: PCBs / Pre-drilled enclosure / Jacks / Switch and parts.
As i said, this is the last form of the project and no further developments will be made.

Back in black. This weekend i've managed to finish the GTFO V2 using the new PCBs - as i said this will be the final version and from my point of view no other modifications will be made. Soon this build will be available as a full kit.

EBRAddict what link are you talking about?! The original one?... Pfff that would be quite hard to find. I will post the build document as soon as it will be ready.

DarkRain,

What kind of inductor do you use in your SMPS? I am using a toroid inductor rated at 3 amps, but it takes a lot of space. I like how compact your power supply is.

Thank you for sharing your GTFO information. It has really been educational.

Mike

The Inductor I'm using in my build is a 100uH Surface Mount one with a Ferrite Core, if my memory serves me right..... :thumbsup

I built this pedal about 9 years ago using the attached files. It turned out very good. It still works today,
