Krell KSA 100mkII Clone

[Erlend Sæterdal]

I only see 4 pairs/channel.

I think IT is a mono Amp.

I like the added drivers to handle the extra output devices.

You must have a tough load needing some attention ��

Good catch. Big monoblocks. Impressive.

hi.
i really like the sound of my krell's. very powerfull and really smooth class a sound.
i use 16 transistors per channel. no changes needed. just lower biasing.
the inductors are for CLC filtering in the power supply.

Hi Fencki,

Which PCB did you use i could see some writing but is there a link to this one ?

- it is good to see people making high quality diy amplifiers still, with the amount of rubbish which is around now !

I have just started a new project.....

KSA100 MKII clone, so far I have nearly all on board parts including the output stage.

I am at the point of deciding on what type of case to use.
I will be using passive cooling but not sure which one yet.....

After some cutting and drilling I made the small on-board heat sink a suitable size, I found a nice extrusion for the other on which I cut down.

Otherwise, really nice looking unit. Kudos.
