Memory Taiwan chipproma nineties.

Amplifier chip TDA 1555Q. (Chip 1997 release, gee). Soldered tonight, about one hour, with entertainment purpose and a meditation on nostalgia. The inclusion of speakers - bridge, ie 4 channels are converted into two, roughly 20 watts per channel. The sound quality is excellent ... Well, for a single-chip circuits.
The scheme is simple, from binding only two ceramic capacitors of 1 uF and one electrolyte-trehtysyachnik - it enhances the filter in the food chain. Although it is possible, and without him - he then, as it were for the Ponte and solid appearance. :)
The desire to make this amp came to me suddenly when I saw the old heatsink from an old amdeshnogo processor. All of a sudden thought - that would tie him to the chip, as in the old school good times. Almost is not heated, incidentally. Could be in lieu of a hefty plate radiator do compact aluminum unit with a north bridge some sort of a dead mother ..
