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.
