Johnson (not his real given name) Tang IS Sanway, which is the name he selected for his company, which sells various pro sound amps and speakers that are manufactured by others in Guangzhou and other Asian countries, which have a go-zillion such manufacturers.
When it comes to tech issues, JT is completely clueless. He basically acts as interpreter as virtually none of the amp engineers speak or read English. This means basically that you're on your own to troubleshoot clone amps, then order any parts you may need, as determined by yourself through whatever channels, from JT and hope they match the original parts. He has little if any leverage with the manufacturers and, especially if he doesn't know what exactly to ask the engineers, will get a "go away, we're busy" response from them.
For example, the output transistors (there are like 36 of them) might be black market copies. Many of them aren't built flat, so don't lay properly on the "copper" heat sinks. Especially with a fan mod, if they burn out they may cost as much as you paid for the amp to get authentic replacements. All of the components and boards in the Chinese amps may change without notice and JT may source different manufacturers at any time without notice.
Since the front panel and case design (which are a patent infringement, BTW) are exact copies of the LG amps, you have no way of knowing what parts are inside the amp you'll get or who manufactured it in what country, despite the fact that they all look exactly alike on the outside.
I'll repeat MO, FWIW again here:
notnyt pinged me when he first found the clones. He was looking to source from one of 2 of the 'agents' who sell the clones. I suggested that they were less reliable and suggested he ping JT. After we compared interior components pics from those 3 agents with pics from amps I had already purchased, it became obvious to us both that what you may actually receive is a crap shoot, so...
He offered to act as middle man for a small fee to receive, open, check and test the amps before forwarding to whomever wished to buy them. This means that he could use the quantities being purchased to leverage JT against any number of similar agents doing the same thing, some of whom may be better interpreters than JT or hungrier for the sales, etc, etc., etc.
There were no takers, to which I reply: W-O-W!
So, if you wish to purchase a patent-infringing clone for 1/6 the price of the real deal on your own, strictly based on the idea that everyone else is doing it and from the same guy, have at it and take what you get and go from there.
There is zero guarantee that JT will have a site next week or be able to be contacted or do anything to help you in any way. Never was. Isn't now. Never will be.
There are at least a dozen such agents who sell the same products JT sells. The amps may be built in China, Thailand, Malaysia, or other. None of the amplifiers anyone has purchased from JT say where they're made anywhere on or in the amplifier. This I know because I have a dozen versions of these switching amps from different agents and have tracked down the actual place of manufacture from all of the Asian countries mentioned.
My opinion is, and I mentioned it to not back when, that he should not have started this thread as he did and should just have made the offer to act as stateside middleman. One reason is because I knew that just what is happening would happen. There is no organization here, only info as to where and how to purchase. As one simple example, why hasn't everyone opened his amps and posted hi res pics of the PS caps, boards, transistors, fans, fuses, etc., so that everyone who purchases could look into whether or not he was hosed? How do you know you received the FP14000 and not the FP7000 or K12000?
If it's every man for himself, which is what this whole amp thing seems to me to have evolved into, so be it, but as an onlooker it pains me to see the lack of organization because it always ends with someone getting the banana when it probably could have been avoided.
