Its been about a year since I first built this website, and quite a few RedRoo amps have been constructed in that time.
As far as I can tell, all the amps built have been great performers and trouble-free. I had the chance to do some tests and voltage measurements around some amps with lots of daily use, and they were all still spot-on.
After embarking on what was basically a hobby project, I quickly realized that there was a lot more time required than I had available, especially for social media promotion not to mention putting the kits together - much more time than I wanted to spend in my somewhat advancing years! (I'm also involved in yacht racing and ham radio, and I'm still professionally involved in the medical alarm industry. Not to mention building an extension onto my Daughters house just outside Sydney this year).
So, I've decided to put the entire design and construction details up on this website as a free download and see what happens, and to offer for sale the parts that can't be sourced directly from Jaycar or Digikey.
Good luck if you decide to build it. Please let me know how you go and if you have any good ideas for improvements.
p.s. I expect to put some other oddball designs up on this website: 60+60W Circlotron amp; 30+30W Murray amp: and maybe my 250W Class-E 40mx AM transmitter with PWM modulator.
