Motorola Class AB BJT Amplifier – Free PCB design Downloads
Build and experiment with the Motorola BJT Amp discussed on my LinkedIn profile back in November and December. Download the KiCad files for free from my Github repo: https://github.com/ufelectronics/classAB-motorola-PCB-layout If you missed it, I once shared the KiCad file for simulating the Motorola AN-484A transistor amplifier. Now I’m sharing the KiCad files for…

Free KiCad schematic for a 50W to 145W Audio Power Amplifier
This is a basic high power audio amplifier constructed by Bob Cordell. Understanding this audio power amplifier sets the ground for understanding high power, transistor based audio amplifiers. – That is my experience. In his book ‘Designing Audio Power Amplifiers’ you will find detailed explanations on how the various parts of it work. – Very…

Uneven DIY coils for RF are a past
Winding them with bare copper wire: * They won’t get an even distributed spacing * Handling them, changes their inductance * They partly uncoil again, as you let go Nothing is controllable. Until you take duct tape, alias ‘Panzer-tape’, alias Gaffa and what else you call it. Take a random object with the desired diameter.…
