Happy New Year Andrej! What is the dimension of your heatsink? It looks nice. Where did you buy it?

Cheers,

Fred

Andrej,

Congratulations. Simply wonderful build. Only comment is components are so dense on the PCB need to be expert to solder, probably difficult repair later.

Thanks,
Routhun

Thanks, Happy New Year to you and to all DIY forum members too.

Both type of heatsinks description in attached pics.

Well I bought them locally at representative of the Fischer company here. Look to their web site to find local distributor and than some CAD/CAM company to grind/tap the heatsinks.

Thanks Routhun

The concept of this amp is high power bandwidth so the parts have to be close to each other because of the shortest track connections as possible. Density of the parts population on PCB is medium to large, parts are having enough space not to touch its neighbours. Of course it is compromise between assembly/service and performance but anyway it is well defined one.

Hi, happy new year, LC

The attached picture is the circuit i'm going to build (ultra low gain), could you help me see any problem/lack in it ? I'm going to construct based on that.
Planning to have 14mA on MJE pairs, and 27mA on NJL pair, is it ok ?
