Medium Power Linear Power Amplifier For LF/MF G4JNT Feb 2013 This is an updated version of the LF Linear amplifier described in [1] After giving that amplifier to G0API to use on PSK31, I decided I did actually need one (to work him with) so this updated version was built.
Homebrew Mosfet Amp Build - QRZ Forums
https://forums.qrz.com/index.php?threads/homebrew-mosfet-amp-build.538277/
KF5MSU Ham Member QRZ Page. I'm in the design stages of a Mosfet Amp Build. I'm having trouble figuring out how to bias the mosfets and how to setup a matching circuit. Not quite sure at this point which mosfets will be used in this build. I'm looking at either the IRF520 or the ERF7530. Any help with these problems would be greatly appreciated.
70 Watt MOSFET Audio Amplifier Circuit
https://www.electroschematics.com/mosfet-audio-amplifier-irf9530-irf530/
The efficiency of this amplifier is 70%, distortions at cut frequency were at most 0.2% at 20Hz on 8Ω and 10W. With a power supply of ± 30V the mosfet audio amplifier can deliver 45W on 8 Ω and 70w on 4Ω. Remember that this audio amplifier is not protected on short-circuits so everytime you switch on check to see if the speaker is connected.
