PUNCH amplifier: 1W guitar amplifier
I've started this project as an alternative to the infamous ROG's Ruby amp. I built a few Ruby's but I didn't like the frequency response of them. It uses a JFET buffer with a MPF102 and the 1W TDA7052 chip. It is a clean amp and it reacts very well with any pedal in front of it. Continue reading...
The "triode" emulator revisited
After reading the excellent page at http://www.runoffgroove.com about the
Fetzer Valve circuit and the
paper that supports it (Dimitri Danyuk, "Triode Emulator" 116th Audio
Engineering Society Convention, May 2004 in Berlin, Germany), I wonder how the
results in that paper could be obtained analytically This page contains my
impressions on it. I've found that the exact value of the magic constant is
. Continue reading...
The Bulbamp
I've started this project with the idea of designing a solid state 1 Watt guitar amplifier and ended up with this 3 resistors, 3 capacitors and a mosfet in a class A configuration and, of course, a light bulb. Continue reading...
