Some pictures of my own project, a stereo Bi- Amping amplifier based on the DaDa JPE modules. You see four 405 modules, two double power supplies and four delay units. The delay units are stacked in pairs. The transformer is a custom build Amplimo. The units run on 60V supplies, the aim was to make the amplifiers less sensitive to load changes, not increasing the output power. The units are still 100W at 8 Ohm at nominal input. There is only one switch at the back and no indicators or whatsoever on the front.
There are some led’s on the inside for control purposes. We are not planning to make these amps on a commercial basis. But............Joost Plugge
Wow Stefaan,
ReplyDeleteyou really know how to work up an appetite....
Brian.
Why not have 4 Toroidals, one for each board? .... ;-)
ReplyDeletePlanning to get my dual Toroidal-dual mono 405 project up on a blog in the new year..(all inside the 405 case!)
Happy holidays to everyone at dada...

Hello Joel,
ReplyDeleteI want the amp to be as compact as possible. The combined transformer only ads very little crosstalk. The rest of the suplie components are all individual for each amplifier.
