Tips hemat & prosedur pengisian tinta Epson L100

Kebetulan sudah 1 bulan ini beli printer Epson L100.  cari2 artikel seputar Epson L100 buat jaga2 kalo bermasalah. Printer ini sudah build in tabung infus dari pabriknya, jadi jaminan lebih bagus daripada sistem infus konvensional, Namun sayang, tinta botolanya masih agak mahal,  sementara kalo diisi tinta merk lain tidak akan jalan.

Kenapa tidak jalan? Karena setiap tinta habis, indikator pengisian ulang tinta harus disertai serial number yang berbeda2 yang  tercantum pada label botol

100Watt Power Amplifier Using TDA7293

The TDA7293 Power Amplifier circuit is conventional, and is very simple because all additional internal functions are unused. The LED is optional, and if you don't think you'll need it, it may be omitted, along with series resistor R3. All connections can be made with plugs and sockets, or hard wired. In most cases, I expect that hard wiring will be the most common, as the connectors are a pain to wire, and add unnecessary cost as well as reduce reliability.

20 Watt Class-A Power Amplifier

The amplifier circuit uses the basic circuitry of the 70W power amplifier, but modified for true Class-A operation - it should be pretty nice! This amp has been built by several readers, and the reports I have received have been very positive.

With simulations, everything appears to be as expected, but although I have yet to actually build it and test it out thoroughly, no-one has had any problems so far. Using +/-20 Volt supplies - either conventional, regulated or using a capacitance multiplier, it should actually be capable of about 22 W before clipping, but expect to use a big heatsink - this amp will run hot.l.) 

300W Power Amplifier For Subwoofer

The 300W Amplifier circuit is shown it is a reasonably conventional design. Connections are provided for the Internal SIM, and filtering is provided for RF protection (R1, C2). The input is via a 4.7uF bipolar cap, as this provides lots of capacitance in a small size. Because of the impedance, little or no degradation of sound will be apparent. A polyester cap may be used if you prefer - 1uF with the nominal 22k input impedance will give a -3dB frequency of 7.2Hz, which is quite low enough for any sub.

70 Watt Power Amplifier Using 2N30055|MJE2955

The 70 watt amplifier circuit is pretty much original, and with a +/-35V supply as shown, will provide 70W into 8 Ohms quite happily. In its lifetime, many of the mods mentioned above were made anyway, since I could never find the circuit diagram when I needed it, so often made it up as I went along! It is a fair testament to the amp that all sorts of resistor and capacitor substitutions can be made, and it still works fine.

30W Class AB Amplifier Circuit With TIP3055/TIP2955

This amplifier has been simulated extensively, although I haven't built it yet. I am saving circuit this one for a time when I can spend good time building and making sure the wiring is going to be optimal. I am going to use this amp in a bi-amp situation with passive filters on the input. This will result in two amplifiers that amplify the highs and two amplifying the lows (for stereo) and thus I can achieve an effective power of 120W into each speaker.

14W Class A Amplifier Circuit Using 2N3055

This class A amplifier circuit requires a preamp as it hasn't got much gain. It requires big heat sinks and a large transformer and a great power supply and careful wiring, but in the end it is extremely simple and it sounds very good. The zener diode rejects any ripple coming from the power supply, But you still only want a ripple of 10mV max. The ripple reaching the input is amplified, so the zener gets rid of that, but whatever ripple there is will still reach the power stage.
