Here are the beginning stages of the development of an audio amplifier invented by Eric Dollard, which is not a voltage gain amplifier. Just about every commerical amplifier is based on the early 1920s RCA patents. John Bedini developed the feed forward amp, McIntosh advanced the output transformer and a couple other innovations, but no matter what, they’re all still voltage gain amplifiers. Those are the best in their own respective category but what we’re moving into is something different altogether.
The amplifier developed by Eric has a longintudinal network and some other features that are not only not used in all the amplifiers, most audio engineers are completely unaware of some of these aspects. The main, full feature amp will be used to amplify Earth signals but there is a simplified version that will be for commercial use. Once we have a few custom items in hand, the goal is to get it wired up and tested. There might be a few tweaks needed for it to be ready for sale to the public, but the primary intent is to generate funds for EPD Laboratories, Inc. and to extend Dollard’s legacy into another area.
The commercial audio amp application of this technology has been discussed a few times on some calls, etc. but the decision was made to finally move forward with it so its the EPD Labs project that I’m the most involved with. The schematics are blurred out in the video because of the proprietary nature of the amplifier but there is enough to show where we’re going with it.
This commercial amplifier project is 100% funded by Emediapress.com – no donations are used for it’s parts, materials, etc. All donations are only used for the other projects that are being showcased in these blogs, videos, etc.
