22 lut 2024 · I have built 3 tube amps using the point to point wiring method. I have built a mullard 3-3 where I could base myself on the mullard book. My other 2 builds are based on a schematic (an EL84PP and a tube preamp) and I had to figure out everything from there on.
Simple and quite similar design of most hi-fi and guitar circuits enables us to use modular approach in tube amp building, using PCB modules. Studying the schematics helps us to design PCBs, where there is no space wasted with paralelled elements, but follow the rules of trace routing.
25 lut 2021 · I use KiCAD when I need to make a PCB, but the schematics are rather 'dry' (simple example attached). Another free option is ExpressSCH, which is a little easier to learn, and does a decent job of making readable schematics.
2 maj 2017 · I'd still like to see a schematic from a pcb layout program or a simulation program that is is as readable and clear as the 'ElCheapo' schematic above, or for that matter as readable as any of the old Fender guitar amp schematics or Heathkit schematics.
The goal is to provide a simple interface and enough power to let the user draw schematics, board/chassis layouts and guitar wiring diagrams quickly and without a steep learning curve. Also, it is build around the flexible open source framework that may be used to draw pretty much anything.
19 lip 2015 · We continue with simple tube-based input stages for use with inverting chip power amplifier, such as the LM3886; think fancy gainclone amplifier. If you thought that I had exhausted all the possible tube-based circuits with my last post, you are not alone, as I thought I had as well.
DIY Tube Amp Schematic – Power Supply 1 of 2. The second sheet takes the output of the voltage multiplier and uses that to supply a positive and negative rail constant current source, or CCS. There are different applications of CCSs in a DIY tube amp. In this case I believe they serve two purposes.
