These boards are designed  for denonstrating amplifier action in Standard Grade (Telecommunications and Electronics) and Intermediate courses

SIMPLE AMPLIFIER A very clear easy to use amplifier circuit.  Ideal for pupil use to illustrate amplifier action and measure voltage gain. Simple, clear layout Use virtually any power supply - ac or dc Simply programmed to give variable gain 1 to 10 or precisely fixed gains of 2, 3, 4, 5 or 6. amplifies ac or dc signals dc amplification simplifies gain measurement ideal for LO3 assessment at Intermediate 2 Order Code: 08-002  Price: £10.95 DC SIGNAL SOURCE For use with the above amplifier, a potentiometer board with AA battery holder to generate 0 to 1.5V signal. Gain measurement is greatly simplified using dc signals. Order Code: 08-003  Price: £8.95 AMPLIFIER GAIN SET Order Code: 08-010  Price: £18.50 Specially priced pair of above boards 08-002 and 08-003 POWER AMPLIFIER An audio amplifier with impressive output power, presented as a booster amplifier for a personal stereo. maximum output 1W to 2W (depends on supply voltage and load resistance) output short circuit proof flexible power supply requirements (8V - 12V ac or dc) measure voltage gain, input and loadresistance, input and output power andpower gain "dummy load" provided for measuring output power stereo input mixed to mono by input lead (provided) separate microphone input Order Code: 08-004  Price: £18.95
