omg ...Greek patento again ...Way to go Nikos
I presume that you expect drivers to blow every now and then so that is why you have a quick lock on the heatsink and replacing is going to be done fast ....

Post 1884-1889 how make changes to improve the amp
This is a very good amplifier.
What I have in mind as my question is to listen the amplifier with authentic transistors 2SK134 -175 , 2SJ49 . there is any difference?
Also never found the original data sheet mimesis 9.2 and the power supply .

Humm, 2SK135/2SJ50...
Nice, but the problem is were to get them
How about a transformer with 1500VA and 2x55V ?

Use 10N20 and 10P20 instead.
You buy them here:http://www.profusionplc.com/pro/gex/prodGen.html?prdtyp=lateral mosfet
Some £5,- each or so. You gain just a few pennies with the 160V edition.
Nice size for transformer.
Much cheaper is this: VTX-146-625-155 - MULTICOMP - TRANSFORMER, 625VA, 2X 55V | Farnell Norge
As two of theese will make You a nice dual mono amp.
And for the price of just £33.20 for each, it's a killer.

No problems with the transistors I have about 18 pairs of 2SK135/2SJ50.
The same for the transformer I got it for free, it only weighs around 9Kg.
I'm only looking for options, the plan is to use the components that I have in my parts bin without spending a small fortune.
I'm almost done with the chassis and will post pictures in a couple of days

Just a tiny weeny question here at the very end of this thread:
Any good replacements for the 2N5565? Or do I have too go through my J-FET transistors to see if I have a good matched pair?

According to Linear Systems cross referens: LSK389C

Got the message.
All I need now is an distributor to sell me theese in Norway.
Stragest things really. Soon there is nowhere for Norwegian hobbyists to buy components when one think in a regular store that is. And also difficult to find all one want in a internetstore willingly to sell to Norway.
But there is no way I give up.

And for the couriosity in me to be put to a stillstand:
Isn't the 2SK389BL up to the job?
Then what about 2SK389GR?
Cheap are they too, only around $6,- a piece

Look at #1732. It gives you an alternativ to to use a "real" dobbel-fet.

Got my hands on a pair 2N5566 wich I think I will try to use.
Otherwise I will look around to see if there is any other possibilities.
Will also look at the SK170, if I meet any trouble with my 2N5566.
Just a tiny little thing here at the end.
I see there is some different schematics going around here, and trust me, I really believed that the one named Goldmund Clone Schematics New was the one there was the last edition.
But after having read through the most of the posts here, I frind that the BOM is very much more like the original schematics of the Memesis9.
Could anyone give me a link to the following:
Final schematics
Final PCB Layout
Final BOM
And please links where I can see theese files without having to register to another file-sharingsite or anything else.
Sorry for being so "grumpy", but I am also very, very lazy.
Happy New Year everyone by the way.
