Yep. I know Justin, and the guy from Houston that built the Palomar amps (in this area Houston anyway, there are many other Palomar builders), I have been out of touch with him for a while, hope he is doing ok. I had the old 250Fet and 450Fet circa 2010-2011. Sold a couple to some friends too. They did work, just I have a problem with the extremely low gain of the ERF 7530 devices. Kinda pointless waste of a bunch of circuit board and transformers. I am not against experimentation AT ALL, I am glad people do it. For 12V though, I think everyone should just support MA/COM and use MRF454's. I do hear that HG Semi is coming along with their 2879 replacements though, taking them long enough...
