This amplifier works well and I get good reports on the air. If I drive it too hard though, it distorts, so I have to be carefull with the drive level. The IRF510 is not the cleanest device, but a higher supply voltage (I use 30 volts) and push pull configuration all helps.
The IRF510 is almost like ladies "panty hose" ~ worn everywhere, easily accessed/removed and durable as hell. With but a few components and around 200 to 300 MW of drive it is easy to see 5 watts at the output of an IRF510 Amp.
18 cze 2016 · WA2EBY IRF510 amplifier The WA2EBY amplifier is a famous linear amplifier project published in QST in March and April 1999 by Mike Kossor WA2EBY. As this amplifier can give up to 50W out with 1W drive, it is a perfect pair for my Softrock RXTX amplifier .
13 gru 2020 · Synthesizing from a number of other amateur radio homebrew circuits I have reviewed, I settled on a simple starting point. This is about the simplest possible IRF510-based amplifier I’ve found, and it’s from Experimental Methods in RF Design (EMRFD from now on), figure 2.98.

In this quick video I walk through a 5W amplifier I built up based on this one from QRPGuyshttps://qrpguys.com/wp-content/uploads/2019/08/miniboots_assy_0529...
Out of 37 direct votes, 21 people chose the one on the left to be the genuine IRF510, and 16 people chose the one on the right to be the real IRF510. The Proof is In The Pudding! I’m happy to report that the first IRF510 that I tried from the batch directly from Vishay worked beautifully the first time.
