For PA-1175 we developed a custom 640VA toroidal transformer with a unique cut spiral nucleus: the refined mechanical process makes the nucleus completely stable, cancelling any mechanical vibration to guarantee a terrific effect and perfect insulation, further enhanced by the use silent blocks.
A secondary small 6VA transformer powers the auxiliary functions with dedicated circuits outside of the audio signal path.
PA-1175 is a unique power amplifier: it features an adjustable damping factor technology that you can easily select straight from the frontal panel.
Changing the Damping Factor to 250 or 25 will let you find the ideal match between PA-1175 and your speakers: use a 250DF to get the power and control necessary to drive large, difficult speakers or set it on 25DF to use it as a low power tube amplifier, perfect to drive high sensitivity speakers and smaller speakers.
To avoid any RFI and Emi potential issue, we have built PA-1175 starting with a massive solid steel chassis and adding thick aluminium panels.
