Unlock the full potential of your PAS2 Or PAS3 with our expert modifications, designed to enhance sound quality and performance.

These are first class kits using all modern, up-to-date circuitry. We only use high quality film and carbon resistors, capacitors, transistors, voltage regulators and silk-screened printed circuit boards. Each kit comes with all of the parts except tubes, as well as a full set of downloadable instructions. Most of these kits and modifications do require a fairly good general knowledge of kit building and a background in basic electronics would help. They are not recommended for the complete novice.
