Schemat.

I'm building off of this schematic from Mark's blog at: http://tagboardeffects.blogspot.com/2012/01/hermida-mosferatu.html For the two capacitors labeled 470n, I bought .47uF Tantalum caps, which obviously are polarized. I can't figure out which way to put them or if it's even ...

... availability of new tubes of this model is endless. Also, under the goop, exist a couple of 2N7000 diode-connected as in the normal Zendrive or Mosferatu and wired in series with each diode-connected half of the 12AX7 acting like a pair of Schottky diodes. No additional BAT41 used here to obtain ...

This is the spirit I like

Ha ha, one of my new years resolutions was to put a bit more effort in to do some new layouts. I may have gone a bit overboard though!

Slightly off topic... I've just been on your blog, you're like a machine!

Or is it this?

Vero layouts for the 3 and 4 knob versions based on kusi's schematic. Is the voice control on the 4 knob right kusi, or would it be like the Zendrive? 3 knob https://i76.photobucket.com/albums/j6/IvIark_2006/Layouts/Vero/th_HermidaMosferatu-3knob.png 4 knob https://i76.photobucket.com/albums/j6/IvIa...

YES! Nothing beats posting the exactly same as the post right above

I'm guessing here, but if you look at the voice pot on the zendrive and transfer that idea to the mosferatu, I don't think you're that far off...

i traced the older 3-knob-version. "vioce" is just a variable resistor for R5 (lok at the zendrive) about the other "mosferaut"-schematic, i asked alfonso some years agoo about it. his answer: > That design has nothing to do with my commercial product. I just liked the > name so ...

I was looking at it... 2 things:
1) are there 4 pot in the pic? I can't see the second row...
2) what about the voice pot in the sch?

this isn`t the first tubescreamer i traced....

Thanks kusi!
But what is the reliability of this schematic?

from a de-goop-job in 2007...

If I were to guess I would say the Mosferatu is a Zendrive with mosfet clippers only. It definately has a little more gain.

Mosfe(t clippers) ra(t tone control) tu(be screamer type) ... sounds like a zendrive... no really, it sounds like a zendrive.

Tikidrive ancestor maybe?

Forgot to mention, the schematic shows dual gain controls plus both post-gain treble and bass controls, which obviously the Mosferatu does not have.
