If you mean association with the boutique amp company Reeves, there is none. If you mean association with Dave Reeves, the original designer, there isn't one anymore at that point in Hiwatt history, either.
What's the serial number of the amp in question? Check it here: http://hiwatt.org/RegMisc.php
A lot of those Fernandes era Hiwatts were made in Asia, some in Japan, some Korea...at that point, the attention to detail, components, construction methods and the like were not the same as vintage Hiwatts at all. In fact, the Fernandes era Hiwatts are thought rather poorly of by most Hiwatt experts, as well as the "Doncaster" era, because Fernandes owned the rights to the name but didn't have any experience or connection with the original Hiwatts, suppliers, manufacturing techniques, etc. So you get the same circuit (more or less), but all of the components are more cost effective, cheaper ones, and even most of the "USA" Fernandes amps were being made in Asia.
Here's an interesting thread: https://www.thegearpage.net/board/in...igner.1158856/
A lot of people don't like the MG era of Hiwatts much at all, and liken them to an Epiphone Les Paul vs a Gibson Les Paul. That's probably a pretty fair comparison, actually--not in terms of quality, but by that point the circuits were more or less the same, but all of the components (transformers, chassis, circuit boards, etc, etc) were being made by different manufacturers. There were actually some slight changes to the circuit designs when MG took over too.
The Biacrown era Hiwatts are in my opinion great amps that go for much cheaper than the original vintage ones, and the Audio Brothers era are thought fairly highly of.
My rambling post basically means that you're going down a long rabbit hole and that there are a lot of opinions out there. It's certainly not a "vintage" Hiwatt with all of the legendary quality, but it's essentially the same circuit and can still sound fantastic. Sort of like a Fender DRRI vs an original 1965 Fender DR. Or maybe a better example would be one of the Asian or Mexican Fender guitars vs an American one, something like that.
Anyhow 90s Hiwatts can be excellent sounding amps even if they aren't the original Partridge transformers and have PCBs. Use your ears to decide whether you want it or not. Yes, they take pedals extremely well, though quality control at that point was not so great, so individual amps vary.
