The 'American'-spare is currently in the system to test/evaluate it, these panels 'Carver Amazing, Platinum Edition' are now more than 20 years old, but I have 4 spare magneto-stats in the 'American'-spares . The sound is nice mellow and real loud as needed (one American magazine claims the have gone to 118dB).

This is a good/nice read: Carver Amazing Loudspeaker (Platinum Edition) | Stereophile.com

Good catch yes it is actually giving the right circumstances it will do a few light years more. The guys from ATL sometimes play tricks when controlling my system from their home (go figure). I never give them my passwords again

A Jimmy-B good instead of a Carver spaced-out power amp, what heresy !

Look better than Apogee, and most certainly sound better

(Faustrecht der Freiheit, 1st Fassbinder movie i saw, ZDF or 3er netz on TV, mid '70s. Very impressive, and with pretty footage of a DeTomaso Pantera GTS)

Got some nice R-Cores from Japan. They are not cheep though. Over 100,-€ per pc. plus tax and shipping. They are 30VA and give a plus-minus 18V DC supply.
Can be used for the Paradise.

On a another planet i have improved my Transimpedance Tube Phonostage. Noise is now equally low on both channels. One input tube was noisy and had to be replaced. Hiss is surprising low now, enough for my Titan i. I was able to reduce the hum too but i am still not 100% satisfied.
I found that the sound improved a lot when i took away the metal shielding cylinders on the input tubes. There was a glare that is gone now. They do not much for shielding ether, quite the contrary to my surprise.

Cool r-cores JG... any hint on how to get some of those ?

News about TS ? (I will build it for sure)

Hi Frans
Like your mention to Keith Laumer
maybe we need to call for Magnus: https://www.google.pt/search?hl=pt-P...0fighter&tbo=d

PS: Outstanding speakers.... better than Apogee ?

Hi there Joachim,

did you published the circuit of your Tube-Phonostage - where? I´m quite
interested about it. And if you didn´t please do

Greetings Ulf

Ulf, i did not publish the tube phono and will not do in the future out of good reason.
There is lethal voltage inside and even me had a hard time to make it work properly.
Also i am totally occupied with work. One is to support the Paradise.
One problem is to select the tubes. Maybe only 4 out of 10 are good enough. Also the circuit is very high speed and can go into oszillation fast. Tube swapping is absolutely forbidden. It works only with certain, selected tubes. If the builder decides on other tubes the result will be totally out of my control and that will happen.
I am willing though to play that stage for visitors. It is a one off anyway. I build it as reality check to find out if tubes sound better. I can already say that this stage sounds different then my solid state stages. It has tremendoes speed and energy, especially when an event starts. It really draws the attention when a singer starts to sing or when an instrument starts to play. On the other hand the sound is not that super clean, giving an impression of a certain brownish-golden texture bordering on the slightly hollow and velvety. The solid stage ones also resolve detail better and focus more tightly.
I would say the solid state one win slightly.
The TS on the other hand may make it into something you can build. Basically it is the same topology then the tube stage, single ended, tranconductance input stage, transimpedance RIAA and buffer, single supply, capacitor coupled. It may sound more similar to the tube stage then my other parallel symmetric, direct coupled designs like the Paradise.
