Re: Wolfgang 61 no sound

Hello! I attached some pics if you want to compare. If you look at the transistors on the images the leg on the left is the drain, right? I mean that's where you measured, right? I tried 4,5V and I also tried around 6V. They both worked. Rhythm channel is basically a clean channel. When you increase...

Re: Wolfgang 61 no sound

Hi there, I'm a newbie, so take what I write with a grain of salt. You posted a picture earlier: Wolfgang 61 footswitch wiring Above BIAS8 there's a hole in your photo. The PCB has a resistor marking there but it doesn't mention which resistor. I guess that's why you left it out. I had wondered wher...

Re: Vandal from Hell power supply and trim pots questions

Hi @M.H.Halo Mmh, I think having a cheap tester around for the transistors (like 25€) to weed out the duds is helpful. But even if you don't have a tester, my advice would be to socket the transistors if possible. I usually use sockets for transistors. This way I a) cannot fry them while soldering b...

Re: Vandal from Hell power supply and trim pots questions

Hi mauman!

No no, I'm not boosting output, the output is fine. I'm boosting the input of the Vandal.

And thank you! :-)

Kind regards,
Seb

Re: Vandal from Hell power supply and trim pots questions

Good morning! Finished the Vandal. I had some issue with the transistors, possibly of my own making. I won't bore you with the details, but I think having a cheap 25€ transistor tester around for this build is a good idea, even if only to check that the transistors are working. Main PCB was easy to ...

Re: Vandal from Hell power supply and trim pots questions

Thank you mauman for all this information! Much appreciated! The linked fetzervalve paper seems a bit over my head. I shall read it a couple more times :) Musikding sent a mail that the shipment is almost on its way. So I think I should have the kit sometime next week. I'll post back once I have the...

Vandal from Hell power supply and trim pots questions

Hi all, Newbie alarm, first post :) I searched the web for some information but didn't find any build reports for the Vandal from Hell yet. I ordered a kit of the Vandal from Hell kit from Musikding. The build document is here: https://pcbguitarmania.com/wp-content/uploads/2022/07/Vandal-from-Hell-v...
