Ever wondered what´s inside the HBE (HomeBrewElectronics) Dos Mos ?
Have a look:

HBE Dos Mos guts

Here you will find the:

Yes, you are right, you can find the missing component values ind in the:
AMZ-FX Mosfet Booster project

Sorry, that I didn´t trace the wiring of this blatant clone.

Price ($ 199.--) you will find here:

What's all the Black crap in there?
Silicone?

It looks like it's holding the LEDs in place...

Another one I'm going to sell and thought I'd share first. If you need specific shots let me know.

Looks like the black stuff on the caps will probably come off... try using some common rubbing alcohol on them to see if the black stuff wipes off. Alcohol is safe to get on there without hurting anything. Acetone will DEFINITELY take the black off, but it may very well take of the markings too and can potentially damage the parts, so just try alcohol.
The transistors look like they have hot glue stuck on their faces to cover up the name. I bet it will come right off if you pick at it with a fingernail.

Thanks for the pics!

Could it be tow cascaded jack orman mosfet booster? The trimpot could be one of the 5k gain potentiometers...

I think I already posted the schematic 18 months ago in another thread, anyway here is the
HBE -DosMos schematic (without surrounding wiring)

great, now we just have to get those cap values and tranny numbers. or will that decrease the street value of the pedal?

FYI-i think you can but sharpies at Kmart, and for 5 bucks cash i'll sell you some 100% certified mojo boogers to rub back on those transistors.

I can try to remove the sharpie and glue off the trannies if you guys need or does the old schematic show the values?

I can do it if need be. I just have a lot of boosts and this one is redundant. im not a strat player really but I played this one today for a while with strat-delay-HBe and I couldnt turn the HBE off. It added a sparkle i couldnt get any other way. Its not enough for me to keep it but it is cool.
