Hi guys I have recovered these beautiful valves from an old television destined to scrap. From this I have saved the 6CU6 (h.deflection) and a double.... -
This is a 100 watt basic power amp that was designed to be (relatively) easy to build at a reasonable cost. It has better performance (read: musical quality) than the standard STK module amps that are used in practically every mass market stereo receiver.... -
You can clearly see the three stages found in many audio amps (and op amps today). However, looking at actual audio designs, you`ll find the basic topology has been tweaked and enhanced in a few key locations. Here`s a quick tour of design improvements of.... -
what value of potentiometer will i use for the volume control of this audio amplifier circuit and in what place will i connect that? thank you.... -
Advantages and disadvantages of different power supply technologies as well as the design considerations involved in choosing and evaluating a mains transformer. The pros and cons of external supplies, inrush current control, RF emissions from bridge.... -
