Amplifiers


Designed for demonstrating amplifier action and measuring voltage gain.

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

 

Order Code: 08-002  Price: £12.90

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 load resistance, input and output power and power 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: £21.40
