Hennady's take on the 1969 JLH

NAD's solution;

Siemens BUZAMP shows another solution.

Dear Hennady K.
You should not assume (or imply, which is part of the method) lightly or as a method that your counterpart might not have registered something.

That would not be wise.

Let's continue:
I made additional radiators for the electronic filter from the remains of the radiator. Now there is a radiator with an area of 324 sq. cm. but in the amplifier case this will not be enough for cooling, so I made another radiator of 108 cm2.

now the total radiator area is 540 cm2

this is already enough to place the electronic filter unit in a closed amplifier housing.

I would love to build Hennady’s version of JLH, but I would need a PCB and some guidance.

 

[The Prof]

I would suggest that you build one channel each of both the Classic 1969 and the HK version, and do a comparative audition.
As I have not built the HK version, I am sorry I cannot be of much help. Surely others here will be happy to guide you.
