Hafner DH 101 / RS 2 Preamplifier

[Seanudal]

Hi,

I have 2 x RS 2 preamplifiers which I built in 1990 along with the V8 250w mosfet amps and reference 4 speakers.
They all still work really well.

I see the RS 2 preamp is almost an identical Hafner DH 101. I have the original RS documentation from Mr Jacobs with the component list, PCB overlay, specs, schematics .. etc. I looked at the DH 101 and it is almost identical.

I am thinking of building this preamp again however will better components. I see someone on this forum changed the caps. Has anyone else built this preamp with improved parts?
