These amplifiers are still valid and will satisfy lovers of the "bipolar" and those wishing to embark on the realization of a way "serious" quality.
In November 1980, Dominique JACOVOPOULOS published in Radio plans a series of bipolar amplifiers TURBO .
Here are excerpts:
* Amplifier TURBO 50
The amplifier TURBO 50, 50 Watt/8Ω

* Amplifier TURBO 75
The amplifier TURBO 75, 75 Watt/8Ω
The article is available:http://cid-2e899d20263c980b.office.live.com/self.aspx/Public/Amplificateurs%20bipolaires%20TURBO/TURBO75%20v2.pdf
* Power supply
This power supply is adjustable from 30 to 40V/3A and allows to connect the two channels of a TURBO 50 and TURBO 75.

* Amplifier TURBO 100
Turbo 100 output power 100 Watt/8Ω
In January 1981, published in Radio Plans # 398 the 100 Turbo.

* Amplifier TURBO 25
TURBO amplifier 25 Watt/8Ω

TURBO 25 regulated power supply (polarity shown here)
Chemical charge a capacitor to smooth voltage at 100 Hz has too much work to undergo more random shocks for a long time. Its longevity depends greatly on operating conditions, performance related to them.
TURBO in the diet, the filter head C 1 assumes the thankless role.
But the sound is extracted from C6 is charged at constant voltage by the voltage stabilizer interposed between these two chemicals. Here we have a system with rapid transfer of energy under the control of the valve that is the electronic ballast transistor. This ensures the best performance in chemical output that does not suffer as current variations.
