High Quality Ceramic Valve Bases

All of our valve bases are of the highest possible quality, made from steatite and using the best metal parts from alloys which retain their spring tension around the valve pin for longer. They are recommended as upgrades to most old valve amplifiers and should be an essential part of any DIY project.

New Product

I am happy to announce that we are finally ready with the first of our own valve bases, see picture below, I have long been unhappy with the quality of the UX4 bases I have been able to buy and decided to look for a supplier who could make a base to our exact specification.

They cost £ 12.50 each plus taxes whereever you are.
