Default Big chance to show off

I built this a couple years ago. It's a Pass A75. Pretty standard except the VU meters (Scales are in German) and the chassis. It was built for and now lives with my German buddy in Florida in a well air conditioned living room.

Default Solid State Speaker Relay

This is one of my current side topics.
A fully isolated solid state speaker relay.
It offers distortion below -120db and is capable to operate even in high power amps in the range of multiple kW and rails up to +/-100V.
Of course it is also very well suited for class D, not only solid state.

And most impressive: Choko went for a proper PCB, instead of his bad attitude of doing everything with P2P wired protos.

Hopefully some of you guys are doing both. We need the clean energy and ... well, the clean energy

windmills

good idee only I think co2 was some day in out admosfeer, al the oil was plants and animals, in the begin of the earts days there was a lot of co2 and
it was a paradise, but later, more and more plants and animals take co2 and
put that in the fosiles like oil.

so if we don,t stop oil use we go beack in time and that means less soil to live on, because everithing is started in the sea.

oke, on topic now, here is a design of the topamp, what i made for someone here.

See the pictures.

This is a full bipolar version that uses Jung regulators and local bipolar buffers. It is also high impedance (default 47kohm), while the input current can be trimmed to under 50nA. No caps in the signal path.

Full measurements to follow, but here's the first noise measurement. RIAA correction is not installed, gain is a little over 80dB (will be 60dB @ 1KHz after RIAA correction). Bottom line - 0.28nV/rtHz.

Distortions are much better than in the HPS 3.1 JFET, I suppose because the large (8 x JFET) nonlinear Ciss is now missing. Overall, about 70ppm at all frequencies and output levels, up to +/-20V. HPS 4.1 has the same headroom of 32dB.
