Wonderfull news.... I love Krefeld and also Duisburg.

I also like reed tonearms... never heard about the russian tube amps.

What cart will you be using ?

As for the speakers, I already read about them... Splendid work Andres

Although I am sure this has been asked and answered several times before - have mercy, I don't wanna skim the whole thread:

How much current will one channel of Paradise R3 draw (per rail)?

According to my notes it is about 80mA (the CCS is set to 110mA).

So total current consumption will be 160mA right ?

Andres will bring an unusual cartridge. It has only 0.25mV output and 65 Ohm. That is because the windings of the coils are not on magnetic material and the magnet is far from the coils. A tough combination. I hope it works with the Paradise.
One advantage of that cartridge is very high channel separation to high frequencies, at least that was told to me.

No. 110 mA. The 50 mA "overshoot" will be burnt by the shunt reg.

???

80mA per side(+-)... each channel has two shunts running at 110mA

I believe total shunt consumption will be 220mA per channel but each channel amp needs 2 x 80mA to operate right ?

In each side(+-) the shunts will dissipate 30mA more than the 80mA needed right ?
