Krell KSA 50 pcb

Hi,

I have schematic of Krell KSA 50 - it is great amplifier, but I need pcb for it. Maybe someone can project this. I'll send circuit on email.

Here is schematic.

Very interesting. I wonder how the KSA-250 differs from this. more output transistors for sure but....

I can make the PCB-layout

I'm working on a KMA 160, which is interesting to constrast with the KSA schematic you posted. For one thing the KMA has an (unprotected) FET input. For another, the KMA uses a regulated supply for the front end and a separate bulk supply for the output.

What's the timeline? When was the KSA 50 made? The KMA 160 is from 1989.

Hi ACD,

would like to see a pcb layout for KSA50, will it be a single sided?

KSA 50 is from early 80'.

As I see it, it will be single sided (easier for the diy-people)

I am interested, keep me/Us posted!
