CAST-PIO-Cu (Copper) 630VDC (for Tube Electronics) Coupling Capacitors 


The construction builds on the foundation of our Virtual Stack Foil design but does so with the addition of a proprietary WPIO  (Waxed Paper In Oil) dielectricum which necessitates several days of impregnation under high pressure.  This creates a form with significantly improved damping properties compared to the already excellent Virtual Stack Foil capacitor giving a mechanical stability hitherto unheard of.
