DIY – Elektor Q-Watt

High powered amplifier inspired by Elektor’s Q-Watt and forum for those expanding on results, performance and their own builds. Interesting subject because of the power transistors MG6330-R / MG9410-R and National Semiconductor / TI LME49811 which is used in the input stage, with the ability to drive a 500W 8 Ohm output stage. Sadly the LME49811 is now end of life without any equivalent. As a side-note for those that have built these amplifiers let us know of any workaround you took if you could not get the chip but you had the boards.

DIY – Radio tubes, pre and output stages

Radio tubes were phased out in the 60s weren’t they? As a matter of fact, not! Many guitarists prefer the tube sound. Along with the return and popularity of vinyl many enthusiasts are opting for the tube sound. Are they really better or just pie in the sky?

DIY – Guitar Amplifiers

Thanks to Bothead’s request we have added a guitar amplifier enthusiasts forum here. Bothead, I pray that you add some input 🙂 For the rest, South Africa has some pretty decent local music, actually world class. We know that there’s a whole bunch of people building and fixing guitar amplifiers. This is for you.
