Krell KSA-100 class A clone:

[hydrovac]

Hi all,
My on going amp build... completed couple of amp projects (Jean Hiraga 30w, Krell KSA-50 clone) recently but was lazy in posting build logs.

The modules:


Trying a new heat sink profile on chassis...


Two heat sinks joined side by side... weighing 5kg per module.

Bottom and back plates 3mm thick...

Face plate 6mm and top plate 3mm...

...

Nice ! How do you source your required dimensions of aluminum plates ?

 

[hydrovac]

Buy bulk sheet and laser cut (job work) to custom sizes.

Super! Having heard the very musical sounding KSA50, can't wait to audition this monster.

And the heat sinks?

Module mounting process on heat sink... M3x12mm standoff.

Power transistors clamped with 8mm sq aluminum bar....
