JA120

This is an amplifier which works in "push-pull", triples load and autobias.It can work with various types of penthodes: KT120, KT90, KT88, 6550, 6CA7 or EL34.

The function phase shifter is assured by a triode double ECC82 and the function driver by an ECC83.It can work in symmetric mode on option.The output transformer, guaranteed for life, allows an adaptation of impedance from 1 to 16 ohms.

The cathode circuit is protected by an individual fuses.
The power transformer is oversized for a better dissipation of heat and vibrations.

The filtering of the high voltages is assured by high capacity capacitors. 
Heating the tubes is by alternate current with balance and noise reduction.

Output terminals allow a bi-wiring.
Gold connections assure a faithful broadcast of the signals. 
JA120
The device is assembled with conventional cabling "point by point" and uses a silver / copper tin solder.
The frame, in non-magnetic stainless steel,  protects the device from external disturbances and does not influence the internal electronics.
