For a long time preparation and hard working , here ,I have finished this proj :
the Krell-Ksa100MKII clone .these are some photos , any advices are welcome.
the bias current was adjusted to 500ma , metal heatsinks' temp stay at 50 degrees Celsius .
The amplifier is powered by a 1200VA toroidal transformer , double independent winding which charges 4 * 68000uf/63v RIFA capacitors.
power-supply soft start.
I match output these output devices to within 2%.
2SC2856/2SA1191
IRFP9510/510
2SC5171/2SA1930
MJE15030/31
MJ21193/MJ21194
CR300

It would appear as if their currency value is similar to ours. That is actually quite cheap, all considered! I have tried looking for those boards, but all the links posted elsewhere appears in chinese. I'm a bit rusty 😀 😀 😀 so can you guys give us info in English?!

I am willing to help you, but the shipping cost quite to be high,
You thought how many PCB the value is?

Hi zly1980,
I'm curious to know how much a pcb would be. Depending on price, I might take 4. Do you supply parts as well?
Again, I'm just curious about the price so far and would like to have more details on the pricing.
Shipping is not so expensive if your use standard HK airmail (not EMS), I've done this before.
If you could point me to an english link for more info, it would be really helpful.
Thanks a lot
Gert
