06.06.2021 New pictures and G8A prototype
You will find a number of new pictures of headshells and combo cabinets designed and built by MADAMP customers in the "Design your MADAMP" area - thank you for all your ideas and the provision of pictures!
And the final prototype of a new DIY kit is done - the G8A is an 8W Class A PP Amp with 2x 6P1P and 3x 6N2P valves, allowing flexible classic rocksounds from clean to crunch w/o ear crashing volume...
28.6.2020 Sound Test G3 Rock
A quick & dirty test at a rehearsal, hard to believe that 3W are enough to compete with drums and bass :-)
Please check my youtube channel ("Martin Madamp") for this video and more sound samples and videos of the G3 Rock...

Last measurement at the test amp, all working as designed...
20.3.2020 Recommeded speakers for the G3
There are too many guitar speakers to test them all - but from time to time I try some speakers. My current favourites with a good value for money is the WGS Veteran 10 for the G3 Blues and the Celestion VT-Junior 10 for the G3 Rock.

See section "MADAMP Modifications" for my opinion on this...
01.02.2020 G3 Rock Development
We're moving forward - the G3 Rock prototype is ready, the last measurements are just taking place. The chassis ist the same as for the G3 Blues, so the data is similar though the circuit is different:
- - 3W PP power stage with a 6N6P, Kathodyn PI with 1/2 6N2P
- - Preamp with three stages (1,5 6N2P)
- - Gain, 3 band tone control, master volume
Next step is building the first test amp, then the first round if tests with guitr players will start.
