The whole page consists of silicon transistors.
The SEPP-ITL-OTL scheme of the pure complimentary darlington circuit which adopted the silicon transistor as the power transistor is adopted.
In order that an electrolytic capacitor may avoid the ill effect which it has on a music signal, as much as possible, using a hardwired-connection circuitry, a capacitor is lessened, and a required fraction makes a circuit impedance high and is using the Mylar capacitor.
Moreover, electrolysis connected the Mylar capacitor to the surely required fraction in parallel, and has improved the high region property.
The triple tone control of Bass, Midrange, and Treble is carried.
Moreover, since it is an it1 step type control, a special NetWare program and a more exact correction of a room acoustic can be performed.

This far I have had two replies, one was in South Africa, that was so expensive it was just not acceptable, another comes from Brasil, a nice one owner amp but again the cost to ship will just price it out of where I want to be!
