Single ended "Mariace" finished
« on: April 19, 2023, 06:53:22 am »
Finally, my amplifier has been able to be finished. I'll give you a test video.I have managed to have treble, mid, bass, reverb, drive and output power controls in the same 5 w amplifier.
Thank you for your collaboration in this project.

Sounds nice! Good job.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Great job and beautiful cab!  I love the sound, both clean and dirty.  Wow. I read your other thread about building it and have a question.  Your Drive knob, is that the Gain or MV pot on the last schematic you posted?  Did you make any more changes after that schematic?  Thanks.

VR1 and VR2 I installed adjustable (adjusted until I liked the sound).
The one that regulates the amount of distortion is "OVERDRIVE 100K-L".
I also made these last modifications that you see in the schematic.
