Products > Amp Audio Upgrade Kits

Our audio upgrade kits offer a selection of the best quality modern production items along with high quality new old stock valves to give you an improved sound and a cost effective upgrade. We have over 30 years' experience with using and listening to high end audio amplifiers and over 25 years in improving the valves. These kits have been put together after many hours of listening tests to confirm the valves performance in any given application.
