High Quality Ceramic Valve Bases

I am happy to announce a further expansion of our "personalised" valve bases the new U8X base, same fine Alumina material as the UX4 base, heavily silver plated contacts as always, sadly again the Sterling prices for all the parts in this section have been increased to reflect general cost increases, plus the severe drop in the value of the British pound.

Price £ 21.60 each plus Vat.

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 and I am pleased to say that here we are.

They cost £ 21.60 each plus taxes whereever you are.

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.
