Circuit Holger (from Germany but now living in Australia) has been using his 405-clone for 30 years but then there was this 18th Birthday-party of his daughter...
Back in the old student days 30 years ago some friends were obsessed with the idea of building audio equipment and one project amongst many others was to build a replica of the Quad 405.
The benchmark was to get better measuring results than the ones published by Quad and following some hard work and applying what was taught at Uni, the result was impressive.
Thanks to choosing better components, using custom built inductors, redesign of the power supply etc. we achieved what was then shared around a circle of mind-liked people.
The unit never failed in 30 years time, but has recently given up following a wild 18's party of my daughter.
Thanks to the team of DaDa Electronics it will hopefully spring back to life and will last another 30 years...
