As many of you know, I for one have stopped releasing all new designs for a few years now after I got fed up with people building crap and claiming it was somehow connected to Kevin or I. Now this also means I don't release the PCB's for many of the older projects as I want to change something and often... make them smaller. So this hasn't stopped people selling crap with our circuits but at least they don't get any of the updates.
Now here is an amp I saw come up for sale in Japan a while ago. The new owner contacted Kevin to try and trouble shoot it but yeah, we don't offer any real help with these things. Something about the PSU did peak my interest so when it popped up again for sale for not a whole lot of money, I snapped it up. So here it is:
Standard KGSSHV here with some version of the offboard PCB's but the build... it is just so bad. All the wires are the same color which is just nuts. Also just cheap PVC China wire and I'll check if it is actually real copper in there. Here are some of my favorites:
Support the sinks properly... that is for suckers. Also I don't know why the volume extender is wrapped in Kapton tape...
The amp shipped like this, the sinks are just attached by the components. It takes no for to bend them like that.
I think this is some form of the GRLV but shit is is cheaply made.
Transformer wires thinner than 24AWG... yeah pure quality there.
Terminal blocks clearly cost too much but stuff like this at +580V can arc over.
Last but not least, no repairs are possible....
What I find truly fascinating about this thing is the PSU board as... well... they cloned my smaller KGSSHV design. That one was never released into the wild but I have posted plenty of high res pics of both sides and they seem to have made a new board from those. See this:
Now all the written markings or most of them, look real. What is not real are all the part numbers as Rxx or Cxx is not a system we use. The packages are all also a bit wrong so the board is clearly a clone. I'll dig it out and post some pics next to the real thing.
More coming as I strip it down.
