The current model of Jadis DA30 is most similar to those Ampliton.
Ampliton Jadis KBL sound tube power amplifier

This amplifier is designed around an alimentation build by Mr Chretien Robert the well know french conceptor and able to drive masterfully any speaker up to 90dB. 

Listening to the sound is dynamic with lots of air and warm. The spectrum is very fluid in the medium with a bass remarkably well developed. Power is present at every moment but this is not to be forgotten to the accuracy and precision.

It is a French amplifier from the 80s of the last century. This manufacturer went against the flow through when putting. A tube amp on the market It was the time when the transistor amplifier with extreme negative feedback and distortion figures of 0.001% as the ultimate product Hifi golden. Fortunately, there were a couple of Frenchmen who were rowing against the current. Well listen, measure and ultimately more with good components and good (and classic *) design brought Ampliton three amplifiers on the market.
At that time they had three models, a 35 a 50 and 80 watts. The first two, the TS3000 and TS5000 are the most popular on the 3rd, the TS8000, I have never seen or found.
There is little to be found on the www, but it seems clear to me that Ampliton with the wave of "L'Audiophile" (magazine) & Jean Hiraga (amp designer) has come along. Today is this by manufacturers as Jadis and Lectron. The current model of Jadis DA30 is most similar to those Ampliton.
Some specifications of the product folder at that time:
- The transformers are generously sized (70 mm) and have grain oriented look
- The heater voltage of the input tube and phase shifter are DC powered.
- Input tube is directly coupled to the phase shifter.
- The output is a push pull circuit ultraliniare.
- The harmonic distortion is 0.11% ..
- The cross-talk between the channels is 65 dB.
- The signal-to-noise ratio (weighted) is 100 dB.

- The rise time is 3.3 uS.
