One of the most acclaimed brands of tube amplifiers is Fender and one of its greatest classics, the Fender Champ. We are designing a printed circuit board to remake this marvel, there are variations of the Fender Champ circuit, the first circuit was the Champion with 5B1 nomenclature of 1948, in 1953 the circuit changed to 5C1, but the best circuit is the Fender Champ 5F1 with an 8 'speaker introd...

Cruce de caminos - Tube amp
* 25 watts, class A, all-tube design.
* 2 channels: overdrive & clean.
* Effects loop via stereo input in clean channel.
* Parallel single-ended power section enables using 2x6L6, 2xEL34, or one 6L6 and one EL34 at the same time.
* Parallel single-ended power section enables producing asymmetric distortion in both power-amp and pre-amp secti...
Class-A Headphone Amplifier using IRF610 and LM317 as CCS.
The original project and overall idea is to [this guy].
Note: Only one channel is shown.Please, also note that the 100k trimmer resistor should be adjusted - see diyaudioprojects.com for more information about that.
Be careful when connecting LM317 and IR...
A high-quality microphone preamplifier using a single power supply, suitable for dynamic or electret microphones. All right reserved to Andy Collison, the author of this preamplifier, more info [here](http://www.zen22142.zen.co.uk/Circuits/Audio/lf071_mic.htm)
A simple dual [TPA3122D2]-based amp with mute switches. One chip is designed to run in bridged-mode, the other one runs single-ended.
The PCB is designed for home etching, the red traces are jumper links.
No liability for lab-explosions or bursted ear drums ;)
