Re: Red Witch Empress [gut shots]

Can someone tell me what the value of R44 is up by the DC jack connections on the PCB? Repairing one and it's burnt. I think I can make out a ?30 or something.

Re: Guyatone - WR-3 Wah Rocker 3 [schematic]

I've got a load of op amps on the way at the moment so hopefully in a few days i'll be able to bang it on the breadboard and see if I can get it working. I was looking at the pot wiring compared to the first schematic and thought it looked a little odd, the one further up this page looks a lot easi...

Re: Guyatone - WR-3 Wah Rocker 3 [schematic]

Did anyone ever get the vero layout on the first page working? I think some pot connections are missing Just look at the included schematic for the pot wiring. VR2/1 goes to ground while VR2/2 connects to C11. Looking at the vero, I don't think it's right. It has C11/222 to ground instead of the po...

There's a problem if you use the "mark forums read" link in the board index page If you wait for the automatic return to the index page, an error occurs: An error occurred during a connection to http://www.freestompboxes.org:80.

Re: MXR Sustain - NOT the nasty Dynacomp!

The MXR Dynacomp (and the almost legendary "Ross" variant of it and all the hundreds of boutique clones) is actually a pretty poor design. The fundamental problem is the OTA (Operational Transconductance Amplifier). In the Dynacomp, it's a CA3080. The "mojo" version of this IC (in its little round ...

Re: Dunlop JDF2 Fuzz Face [schematic]

Oh, and because the thermistor and pot values were missing in your schematic. (where's the post edit button?) Oh, I thought maybe there was something not right that I didn't see and wanted to fix it. I have since completed the schematic more. When I posted that I didn't have all the reference done....

Here's the correct schematic: Which is what I have but the negative of C3 clearly goes to C5 on the PCB. Correct, C3 neg to C5. Thanks.

Re: Fulltone 2B [traced]

Hi BSide, Re the IN750A diodes can I substitute with a 4.7V IN5230B? I cant find any IN750A's. Also what do you suggest for the Germanuim Diodes? Adrian I would assume any 4.7v would work in this application. For reference the 1N750 is a 0.5W/4.7V zener diode. I'd probably start with a 1N34A for th...

So then we can assume the 2B uses the AD711J since it's a single op-amp in there and the TLE2072 is a dual.

Not familiar with the 2072C. Is that the TLE2072? Link to a datasheet?

Re: Fulltone 2B [traced]

Hey, thanks for your work! the gain pot value: you should be able to measure it, if you lift one end of R30; but I see they have bent the legs of all components under the PCB, and this could result in some complications in the desoldering process. You could try and unbend the component legs while d...

Re: Fulltone 2B [traced]

Here's the schematic. Maybe this will spark more interest in this. I'm pretty sure it's correct but I have the pedal for a few more days so if you have any doubts/questions I'll check them.

Re: Fulltone 2B [traced]

In the parts/values list above I wrote R20 and it should be R28. I didn't have my glasses on and the 8 looked like a 0. :D
