Yes you right.
One of the worst caps you can buy today. Many of them blew up after a while or start to leak.
I did tested several value they sound very-very thin compare even to the regular Nichicon not to talk when it was compared to KG or FG type or Elna for Audio etc.
I would right away replace it Nippon CC KMH type...

OK I know SAMWHA is not the best cap, but I would be very surprised if Hypex would be so foolish to risk full bunch of warranty replacement requests?

Nice Heatsinks supernet. What are they rated for ( I.e. C/watt)?

Exemplary construction as well - very nice

Well...thanks, but all greetings should go to LazyCat. I just took camera in this case


Yes, heatsinks are really monster ones, but they are doing the job exceptionally. For this height of 65mm, they are rated around 0.4 K/W. In my living room, where the temperature is now 20C, they get barely warm (speakers are easy 8 ohm load too).

If any interested there are 4 SK157 65mm heatsinks left from cutting. Two are blank, without holes. The other two already have holes predrilled for VSSA installation. For info...pm please.

About heatsinks...65 mm are already reserved. But LC mention that there is one SK157 with 132 mm height available. This is large enough for both channels and has already predrilled M3 holes for chassis and two VSSA mounting. Price is 50 EUR + post costs, which is bargain...


If anyone interested, please contact LazyCat for shipping and paying details.

I've ordered a heat pipe and fan with a pwm controller, to see what temperatures it can control.
