Like I said before months ago. There is only one person that shows a clean envelope from the 2030+ parts. More power to him if he likes them. I don't care for the 2030+ myself. Nobody has shown a comprehensive datasheet for them. They have a large gate capacitance that make them difficult to drive in some applications. And there is always the chance that they could become unavailable at any time. I'm not a fan of the the 13N10s or the 520s either, but the 2030+ isn't my idea of a good substitute. Keep in mind, I'm not a tech, I only work on my own radios and I've built a couple homebrew SSB ham rigs. For me personally, I'll spend a few extra dollars on parts that were designed for RF, and have the associated documentation. It's just easier for me.
Now, the 4 matched 2030+s that I put in my 4400 Turbo amp section, are still in it, and holding up just fine. The amount of time that it took me to figure out how to get them linear wasn't really worth it though. The really low gate impedance/large gate capacitance threw me off. Their performance is fine, but it's nothing to write home about.
Honestly, I think their selling point is that you can buy them in sets matched by their gate threshold voltages, for use in parallel with only 1 bias adjustment, like in a Stryker or my 4400T for instance. I guess if I was building a bunch of radios, that would save me the time of matching up pairs/sets myself, but again, I'm not a tech.
Why are we still being this dead horse anyways? Lol.
