Still here, people wanted the designs for free and to rip of the public, so I am going to put designs for free on some forums, the latest was Pearl Acoustics. Nice guys but want thing for zero.

By using LTC SPICE you can check this odd circuit out. I does work well but the PSU must be very low noise and very well regulated.

How would you stop PSU pumping in a Class D Amp. Most of the techy folk here will have come across this maybe with Tripath chips. So how did you solve it? I will put up and idea that works well and reduce component cost. And no cheating by doing it Bridge Mode OK or limiting the bandwidth to...

The Brief History of my life with SECA designs The SECA amplifier designs have been in use for a long time from the early days of valves to the present day. With valves it was a simple matter of biasing the triode and having a transformer coupling to the loudspeaker. Even the first transistor...
