Like I say often, I like to read. I have been reading all of these forums since they started. It's true that most people who do write seem to do so to complain. Still, most of the complaints that I have read by people that like their FX's have been about their Amp regulators. There seemed to be a big enough trend there that Huma has made quite a business selling replacements that many are willing to buy. And they don't complain about them as much either. I think that while Amp regulators may not show up actually broken, I don't believe that they are as good as Huma's either. I have not read about anybody switching back because of poor performance either. I'm old too, and I can't justify wasting what time I have left on the hope that my Amp reguator is a good one when so many seasoned users have had enough and just get Humas. I just cut to the chase and avoided a potential problem. I was going to completely take down my gun anyway and with what all of this stuff costs anyway,I'm not sweating a different regulator purchase. If yours work well, of course you shouldn't change them.
