Is this layout verified?
I would like to know also. I etched it but I am waiting for a parts shipment.

I've etched the "horus2" version PCB, and noticed there is no mention of r26 in the bom, but it's listed on the layout with no value. Scanning the schematics, it appears to be a 470k. In case any one else builds this version.

Oops, you're right, I missed that.
r26 on the layout = r24 in the bom.

so i've got mine up and running.... not quite as "sabbath-esque" as I have heard. nice and heavy, tho. thanks for the pcb layout.
I gotta try and get it a little darker without introducing too much mud.

There is no "horus2" layout, the second layout I posted is probably what was being referred to.

Yes. I've attached an update that corrects the error in the layout and bom discussed on the last page. See below:

From their description I'd guess it's a pot (something close to 390k) wired as a variable resistor on the input and that seems like it could be useful. The other control they explain clearly but I find it hard to see the point of having six types of diode available on a rotary switch for clipping, trying to imagine the kind of words someone might come up with to describe the differences; louder and quieter might cover it all.

I've posted this, on another forum but I would see gutshots to see if It's what I've expected.
Official Description:
The Supreme has all of the sounds and abilities of the Standard and Primitive Pharaohs, but with some very useful additions and a bit of a twist.
In place of the hi/lo switch,the Supreme utilizes a variable pre input control to infinitely adjust the saturation of the front end of the circuit from 1 to 10. In Place of the 3 way diode selector, the Supreme utilizes a 6 way rotary switch to select from the Standard Pharaoh diode settings, plus an additional 3 setting not available on the previous Pharaohs. The Pharaoh supreme allows selection from the following diode settings: Germanium, Asymmetrical Germanium(standard Pharaoh), Silicon (standard Pharaoh), Mosfet,LED and Bypass (standard Pharaoh).

So for the pre pot, we need to swap the Lo/Hi Switch for a 500K pot I think or something else.
For the clip control, use rotary switch 2 poles, swap the clipping switch on the original pedal and put the diodes on the description below. Just the mosfet is undifined.

I have a special Pharaoh named "custom deluxe". I asked Mark if he could build me on with more clipping option.
It was this build that gave him ideas which led to the Supreme.

The Clipping Switch on the Pharaoh Deluxe:

LSTR style Silicon
Pharaoh style Silicon
Symmetrical Germanium (1n270)
Asymmetrical Germanium (1n34a)
LED
BYPASS

It does not have the Mosfet like The Supreme does.

I made a modified version of this. It's a great pedal but I didn't like the tone controll, so I use a Baxandall. Schematics and video:

Few informations from someone that have an original supreme Pharaoh

Red caps are actually 474
103 and 223 for the other ones
(caps are the same than the standard version)

A100K on the volume pot
A100K on the fuzz pot
B500K on the pre pot

Seems the Tone pot it's A100K too (4C4 written on top), just need the value of high, but certainly B25K.

Mosfet
Q5: BC20 2N 7000
Q6: BD48 2N 7000

Can you check the value of input resistor for Surpreme? If it has one?
I know it has a 500K pot for pre, but I was wondering what happens when the pot is @ 0 Ohms.... woudn't that be a too much input signal?

hi guys!, this is my layout for the Pharaoh Supreme version.
Pots and rotary switch are pcb mounted, component side, it's really thight but it fits in 125B box perfectly...MINI Supreme :)
PCB file and template for the box are already scaled so print as is.
i hope you enjoy whit this build, mine sounds really well!
ciao!
