TH Black Eye (Soldano GTO) prototype build

Mmkay, so I have 3 enclosures on hand that I just milled up, I have 20 more that will be here friday. So if you just ordered a PCB I'll get tracking up tonight, and if you're one of the first 3 that ordered an enclosure I'll get tracking tonight, otherwise I'll get tracking for you Friday night. Also I may as well get a quick demo recorded of the one I built up, it really is the best damn dirt pedal I've ever heard.

This is what the pre-drilled enclosures look like, by the way:

This could be another option , The 1590Q measures 120mm x 120mm x34mm :

Yup, my goal for the project was to make it as easy as possible to assemble and as cheap as possible to source parts. Even if you paid extra for the pre-drilled enclosure, the total cost for building the project should be $100 or less, and the tubes are the most expensive part of that. Everything but the tube socket, tube, and ribbon cable (if you want to use one) are available on Tayda, no reason to pay extra to get it anywhere else in my opinion.

Looking forward to seeing some builds happen, and feel free to hit me up with any questions if they come up :)

Here's a Mockup with 1590Q Enclosure if you want Top Mount jacks? :

That definitely looks like an option. It looks like there would be enough room to move the board up a little bit so you don't have as much empty space up top, especially since the footswitch can go wherever you want as long as it isn't hitting tubes. Look like plenty of room to play around in there.

Yes, this was based on the Switchcraft Enclosed jack pictured on the right.
If using the Lumberg mini Jack below, Everything could move up!

This is a fantastic project. Thank you, @vigilante398.

I'm about to pull the trigger on this, as my first time trying to build something with tubes. I saw in the interview that temol posted that the latest release of the pedal runs on 12V. What power requirements does this circuit have? Thanks in advance.

It can run on 9V or 12V, there shouldn't be any tonal difference between the two. It will try to pull close to 1000mA when the tubes are heating up, but once it warms up it will settle back down to around 450mA. I recommend a power supply with at least 600mA of current.

From what I remember - one 12AX7 = 150mA @ 12.6V and 300mA @ 6.3V. 12.6V and 6.3V it's a heater supply of course.

Yup, that's correct. If you run heaters at a lower voltage it saves you a little current, and I've found that if you run them in series at 9V they heat up enough to run fine, so I typically do that. I did some tests and if I remember right they pulled around 125mA per tube at 9V. The Matsumin Valvecaster does the same thing for 9V operation, but obviously we have the advantage here of running the plates at high voltage.
