The Adrenalin amplifier represents the point of arrival of the INPOL concept.
The essence of such apparatus is that of a tube amplifier featuring a very sensitive and refined timbre, combined with a surprisingly and amazing output capacity.
The monoblock delivers 200W of power on a load of 8 Ohm and uses a layout tested many times by Pathos. In fact, this is a balanced stage, which means that each amplifier is made of two power stages connected with INPOL configuration, intrinsically functioning in class A.
An INPOL stage can work only in class A. It is neither a push-pull circuit (where it is possible to choose how deep to polarize the final stage during the phase of design), nor a single-ended stage; considering the presence of a reactive element that works in symbiosis with an active device (in this case a group of mosfets connected at common drain). INPOL represents an alternative between the two configurations; hence, this topology, created and patented by Pathos, has properly gained its place in the Gotha of Hi-End.
This power buffer with unitary gain, is controlled by a tube amplification stage using three double triodes consisting of two ECC83/12AX7 and one 6H30. The first stage generates voltage amplification based on differential totem pole with two 12AX7. The second is a buffer with a common anode with the 6H30 that has the function of driving two groups of power mosfets. The signal on the two outputs amplified and out of phase between them, is delivered to two buffers with INPOL technology.
