Re: Brunetti Taxi Drive [traced]

ok,i thought you did your own schematic following the actual board numbering,that's why numbers are different.
I can call it verified. :applause:

Re: Brunetti Taxi Drive [traced]

diode could be ba157/159 which is right,it has a Vf over 1v. From what i can see from pics,C5 is on the output of the fet,in place of C13,which in reality is the 47nF on top thats related to the gain stage,near the switch. Another important thing is the voltage on the drain of J201 fet,and on the bu...

Re: Brunetti Taxi Drive [traced]

apart from the 220p cap and 470 ohm source resistor,the rest should be fine,there is some confusion from the numbering of components,recheck that.
Diode missing?
can you desolder it?

Re: Brunetti Taxi Drive [traced]

yes C2 is parallel to diodes and source resistor is 470 ohm.

Re: Brunetti Taxi Drive [traced]

After some desoldering here is my final version with all the values. Could somebody who actually knows some electronics check the schematic on plausibility? Especially the JFET section with the two 1M resistors look unfamiliar to me. Can this be right? C2 should be parallel to the diodes not in ser...

Re: Friedman BE-OD Pedal [traced]

Anything "Friedman" builds should always be labeled "Custom Audio Electronics", cause that's basically where he stole all his shit, do the research. :roll: everybody steals from someone,but Friedman stole CAE products? not at all. the only thing he stole is the business,but ther...

Re: High noise floor on MXR Custom Comp

You won't find any schematic for these pedals.
Only way is oscilloscope or audioprobe following the audio path.

Re: Strange Phase Inverter in Geloso tube amps?

its not popular as a guitar amp because at the time these were conceived and built there were only generic mono amps for microphones,accordions,phonographs etc.
the whole guitar thing happened later with proper choice of eq section,gain,LTPI.

Re: Slide potentiometer for black MXR Ten Band EQ

I'm looking for a replacement slide potentiometer for my black (recent) MXR Ten Band EQ. Dunlop has the sliders for the black M108 Ten Band EQ on their website, but you can't buy them directly from Dunlop: https://www.jimdunlop.com/product/ecb046-7-10137-07226-8.do Part nr: ECB046 Ordering them dir...
