There seem to be different versions. Ryan posted some cool pics in this thread:

http://www.diystompboxes.com/smfforum/index.php?topic=46251.0

Analogguru has a schematic here for a Ge version:

The values Yun posts must come from a third version.

Funny, when we worked on Ryan's pedal, I unknowingly had Analogguru's schematic in my files. In retrospect, I would have just adjusted his schematic to reflect the changed values of the new version.

Maybe you look for comparision purposes at the Fuzz part schematic of the "Acoustic 360" and the "Benson 330H" posted (new) on my site.

Acoustic 360 uses a silicon for the first stage and a Germanium for the second stage.
For the 2 N 1306 you can use an AC127 or similar.

In principle the Orpheum is a copy of the early Mosrite Fuzzrite - you can find inside pictures and a schematic here:

http://eu11.stripper.jp/pulcino/blog/archives/cat_mosrite_fuzzrite.html

also the early Guild Axis-Fuzz used the same circuit, inside-picture can be found here:

http://www.electroharmonix.ronsound.com/gallery/foxey/foxey_lady.jpg

they only changed the input resistor from 10 M to 2x 10 M in paralell = 5 M.

All silicon version used the 100k (in series with 47k) in the collector of the second stage.

when i find some time i will write an article of this stuff with nice pictures.

The Orpheum Fuzz was also sold as the E.U. Wurlitzer "Fuzzer Buzzer":

Cool,
Let me know if you need any pics of the one seen in the other thread for your article.
I am now the owner of that one.

here's my take on this fuzz, i mostly stayed true to the amplifier handbook that i said about in my earlier post....



I just built it like that and it sounds AMAZING!  Much more thicker, and nastier tone.  Think of it as a maestro fuzz-tone with a thicker and meaner attitude.  The tone control sounds very (shockingly) much like the BMP's tone stack....

ENJOY!!!!!

Can you make some samples?

Edit: hum but not necessary with the mod...
I know, but the pedal i built does not boost...it just increases volume!

I've built the orpheum fuzz, it's nice, but for me it is uncontrollable ( I would have built the mostrite, but I've made this and I  wanna mod it  :icon_wink:)
So" the Yun mod" seems cool and I was asking a sample about it....

In what way? Can you describe the symptoms?

It's not easy...By the way there is lot of noise, too trebles tone and I use it only with ds-2 or ts 808...Only orpheum is not a good sound for me.  I've listened the Dragonfly germanium mosrite and it seems really better. Anyway the Yun mod seems good, I believe I'll try it!

All of that style of fuzz are very trebly.  You can try to fatten it up by using a larger output cap.  The Germanium Mosrite will not be much less trebly.  If you want fat fuzz you should build a Fuzz Face.

Swapping the .0022uf cap for a higher value makes a difference aswell. Try a .01uf to start with.

EDIT: On the original schematic that is.
