content: "none of the supplies are grounded"Not through their chassis? The big straps are not copper?Also are the output terminals steel threaded rod/bolts?I was really disappointed that I couldn't find these for sale. Anyone found any examples under another name?EDIT:https://old.reddit.com/r/cbradio/comments/3it1hr/inside_a_new_xforce_200hdm/I'm imagining that one guy is making these, not a whole company.

content: I've found lots of differing opinions on X-force items. Things are all over the place, some comments read like personal warfare, others read as though X-force is a company that participates in HAM events. Perhaps it's a UltraFire situation where multiple people have taken the name? Not sure.I might be right about this being a small or one-man company:https://www.youtube.com/channel/UCTQv7Yu_X1mzi7jHPhMF8ZQ/videos?disable_polymer=1Obligatory: please don't bandwagon and throw hate at this person. Find links to the stuff, discuss it for its problems/merits; but don't attack the individual. Be better than that, please.

content: Looking further it does seem some things are strange here. On one hand we have some videos by a guy that seems to care and know what he's doing; having to repair badly modded transmitters and showing a good sense of humour.Opposing that we have the PSU shown at the start of this thread. X-Force's website lists info about competitions and being wary of fakes. Perhaps we have some unfriendly disputes or competition involved? Look at video replies like this:

content: I can see lots of blobs of solder and that capacitor looks like it is not through hole but stuck on with the solder holding it together.

content: Quote from: Whales on February 11, 2019, 10:54:44 amWhere are those videos of the competent repair guy? (From X-Force, I presume? You realize that the author of the video in the OP isnotassociated with X-Force, right?)Looking at the improvised front panels shown on the X-Force website, I find it entirely plausible that their equipment looks just as messy inside as the power supply and amplifier shown above. No need to assume that any fakes are involved. I mean, who would want to fake thisthing?Edit: Fixed image link (hopefully)

content: There is a guy named Walt Williams that built equally ugly but apparently good quality power supplies.http://forums.qrz.com/index.php?threads/walt-williams-100-amp-power-supply.284529/Although I have never seen one disassembled, looks are not everything.

content: Quote from: rsjsouza on February 13, 2019, 08:42:06 pmI agree. But for me there is a pronounced difference between the Walt Williams supply (unadorned, but functional and symmetrical) and the X-Force example (which exhibits a total lack of planning and care).

content: Quote from: rsjsouza on February 13, 2019, 08:42:06 pmVery true, function over form for me if I'm building stuff for my own use, if I share the design then other people can make it pretty.Having seen the guts of X-Force, Davemade etc. etc. yeehaw redneck muh swing merchants, the guts of those amps and power supplies will all be just as bad as each other.I have little doubt that the Walt Williams PSU bore absolutely no resemblance to them.
