DIY - Power-class Hi-Fi.

           (C) Arny Sinen, 1997



   Since Spectrum is not his, native
amplifier, one has to resort to various
tricks, some of whom are connected to stationary amplifiers, 
and use the amplifier built into the monitor or TV. However, 
not all monitors there is an amplifier (such as me), and

stationary connected not like, and
so I resorted to a simple solution:
you need to put in the computer system unit stereoMINIusilitel, 
the scheme which I you and I suggest below. This power belongs 
to the Hi-Fi class and its short-term peak power can reach 40W 
in each channel, then recommended to him

AU should be a minimum of two-way
and have a short-term capacity of at least
50W.


               2 X 25 Hi-Fi


Amplifier performance:
Upow = 4 ... + 44V

         the best 25 ... +35 V
Ipotr (Uout = 0) = 100mA
Ipotr max up to 2A
Kgarm = 0,03%
frab = 20 ... 30000Hz
RL = 3 ... 16 th
Kusil = 25 ... 40
Uout = 200 ... 250mV

Can also order ready-made amplifiers,
board designers.
The next issue I plan to publish a scheme of the amplifier 1,5 
W (mono). Upow = +4 ... +10 V (Ideal for the Spectrum).
