TRIODE SPIRIT 300B LUXE

The famous 300B was always honoured as much as possible on the range of J.C.Verdier's amplifiers.
It is really a difficult exercise to obtain the best possible musicality with a triode amplifier, because all must be perfect around the tube.
Now we introduce a new improvement in the circuits of the regulated power supply.
It concerns a mounting with 3 additive tubes which tracks all remaining hum, for that reason we call it "hum hunting circuit". And more this circuit reduced the internal impedance to quasi nothing.
This improvement adds to the large number of those existent, it leads the Triode Spirit Amplifier 300B Luxe to a degree of musicality never yet reached. 

The amplifier Triode Spirit 300B Luxe is fitted with 9 tubes used in the following function :

2 X 300B direct heating power triode
2X 5U4 direct heating power rectifier
2 X 6AS7/6080 twin power triode balast regulator
1 X 6SL7 voltage amplifier
1 X 6SN7 cathode follower/driver
1 X 6SL7 Error amplifier and "hum hunting circuit".
