I think that in the first circuit in this topic, you can use the heating coil for multiple stages, but I am not sure.

Dumble Stompbox
I know Dumble is an overall concept, but I should nonetheless like to know who built a Dumble tube stompbox, in particular using the overdrive section as standalone driven by any input boost circuit.

Re: Cap Leakage Tester Schematic
This is my translation of the German article form above, english is not my mother tongue, so please be indulgent to my mistakes. The test voltage is set by the ratio of the voltage divider left. Put in the capacitor you want check, after that actuates the switch. Now the capacitor will be charged. I...

Here the schematic of a leakage current tester,
unfortunately only in German language.

Re: Fender Custom Vibrolux (Distortion Problem)
The Voltage of 70V DC is ok , in comparison with other Fender schematics.
Perhaps there are twisted numbers and a value of 71,4V was meant.

Re: Express: Add gain pot and bypass switch for 3rd gain stage
If the grid of V3 becomes positiv due to a high signal peak, then the sound is influenced, because there is a current flow into the grid. The current flow into the grid causes a voltage drop on the resitors R2 and R3. If the S1 in the right switch position, the right pin of capacitor C3 is not conne...

Re: ExpressPCB issues
I have Windows 10 and all the SCH stuff works fine for me. Of course, I had to download the program again. Have you done that? With respect, 10thtx Yes, I did, but the the newest version is not operating either. I think that is an inherent WINDOWS10 problem, so I have to completely reinstall the op...

ExpressPCB issues
ExpressPCB never runs since I swapped form WindowsXP to Windows10.
The message "run-time Error 13" appears immediately after starting the software.
I tried many recommended fixes and software repair tools, but nothing did work.
Who knows more about?
