Can be directly connected to CD players, tuners and tape recorders. [more]
This design is based on the 18 Watt Audio Amplifier, and was developed mainly to satisfy the requests of correspondents unable to locate the TLE2141C chip. It uses the widespread NE5532 Dual IC but, obviously,... [more]
This is a 100 watt basic power amp that was designed to be (relatively) easy to build at a reasonable cost. It has better performance (read: musical quality) than the standard STK module amps that... [more]
The circuit accosted in those who they want a Vumeter that will be connected in the exit of power amplifier. [more]
Three Tube PHONO (RIAA) Preamplifiers with ECC83 [more]
A very good circuit of pre-preamplifier, for amplification of signals from heads of Moving Coil. It uses the two departments of tube ECC88, association parallel, for reduction of produced noise. [more]
With graphic equalizer we make selective cutting off or boost, of selected departments of acoustic spectrum. With this way we can adapt the musical reproduction, in the characteristics of space where we hear. This can... [more]
