Schematic Tube Power amplifier 6v6 watt
This circuit is similar to the 6V6 Amp except that it has two channels. It puts out about 10 watts into 8, 4, or 2 ohms. Tubes used are 6SN7, 6V6, and 5U4. Negative feedback is taken off the output transformer's secondary.
WARNING!
Tube circuitry uses lethal amounts of current at high voltages. Be extremely careful when constructing any types of tube circuitry. Here are some tips for building circuits safely:
When testing circuits, do not stand on metal or anything grounded.
When measuring voltages in the circuit, use only one hand.
Never work on a circuit while it is plugged in.
Discharge filter capacitors through a resistor after turning off the circuit.
Wait for tubes to cool before handling or removing.
Use common sense and don't do anything stupid.
Note: I am not responsible for injury or death as a result of carelessness in the construction of the circuits on this site.

Schematic tube Power amplifier 3 watts
3 Watt Amps
These two power amplifiers are almost identical except for the brand of power transformer. Tubes used are 6BM8 and 6X4. Output power is about 3 watts into 8 ohms. The output pentode is connected to a 40% ultra-linear tap on the output transformer.

How to "Delete administrator Password" without any software
Method 1
Boot up with DOS and delete the sam.exe and sam.log files from Windows\system32\config in your hard drive. Now when you boot up in NT the password on your built-in administrator account which will be blank (i.e No password). This solution works only if your hard drive is FAT kind.
Method 2
Step 1. Put your hard disk of your computer in any other pc .
Step 2. Boot that computer and use your hard disk as a secondary hard disk (D'nt boot as primary hard disk ).
Step 3. Then open that drive in which the victim’s window(or your window) is installed.
Step 4. Go to location windows->system32->config
Step 5. And delete SAM.exe and SAM.log
Step 6. Now remove hard disk and put in your computer.
Step 7. And boot your computer :-)
6 Input Mixer Schematic
6 Input Mixer Schematic
A simple mixer with 3 line inputs and 3 mic inputs using commonly available parts.
Notes:
The mixer circuit above has 3 line inputs and 3 mic inputs. The mic inputs are suitable for low impedance 200 to1000R dynamic microphones. An ECM or condenser mic can also be used, but must have bias applied via a series resistor. As with any mixer circuit, a slight loss is always introduced. The final summing amplifier has a gain of 2 or 6dB to overcome this. The Input line level should be around 200mV RMS.
The mic inputs are amplified about 100 times or 40dB, the total gain of the mixer including the summing amplifier is 46dB. The mic input is designed for microphones with outputs of about 2mV RMS at 1 meter. Most dynamic microphones meet this standard.
The choice of op-amp is not critical in this circuit. Bipolar, FET input or MOS type op-amps can therefore be used; i.e 741, LF351, TL061, TL071, CA3140 etc. The power supply is a dual positive and negative supply, two 9 Volt batteries may be used as shown above or a power supply is recommended for longer periods of use.

110 dB Beeper
110 dB Beeper
The setup employs a single 74C14 (CD40106B) CMOS hex inverting Schmitt-trigger IC, which must be used with a piezoelectric device with a feedback terminal. The feedback terminal is attached to a central region on the piezoelectric wafer. When the beeper is driven at resonance, the feedback signal peaks.
