• A valve amp is a treasured possession that will be lovingly maintained from one generation to the next. An un-serviceable switch-mode power supply designed to be redundant within 10 years has no hope of lasting the distance. A 12V choke input filter supply will last virtually forever requiring little to zero maintenance.

  • Integrated Circuit Audio Amplifiers By Mike Martell N1HFX. In a previous article I discussed building audio amplifiers using discrete transistors. While it is possible to build good audio amplifiers from discrete transistors, they are no match for the many audio amp IC's available to us.
  • 2) The amount of increase in audio signal strength, often expressed in dB. Gain:The measure of how much a circuit amplifies a signal. Gain may be stated as a ratio of input to output voltage,current or power, such as a voltage gain of 4, or a power gain of 2, or it can be expressed in decibels, such as a line amplifier with a gain of 10 dB.
  • 0-32V Power Supply Connecting the LM338 to the heatsink and use thermal paste. Use external supplies for LCD panels. The transformer should be 50 to 100 Watt.Diodes must be 10-15 A. Output transformer less then 25V AC. Adjust voltage in...
