Some info about us.
Our passion is valve amps. We love them!  We focus on musical instrument and hi-fi amp valves. We don’t forget juke boxes either. We are based in Yorkshire UK and ship all over the world.

Stewart, who runs this site has decades of experience working with valve amps and tries to play guitar. So he “walks the walk” as well as “talks the talk”

You can take advantage of this experience and get advice on ideas to pep up your amp. We have also advised on faults and the a suggested approach to a successful restoration of your amp to its full glory. Just email us at

Her is some info about us. So, we understand that all valves are not created equal.  Different brand names even out of the same factory are deliberately made to give you different tone colours. The challenge is so much choice and so little time ! We have almost 20 variations on the ECC83 ( 12AX7) pin out all with their different sounds.

We supply valves from JJ Electronic in Slovakia and the New Sensor plant in Russia. We are official dealers for Electro Harmonix (EH), Sovtek, Genelax and Tung Sol We buy them direct from the manufacturers and we have all the right test gear to do matching/ balancing of your valves. We test EVERY  valve we sell.

We ship same day up till 3.45pm (to hit the last post as we are located in the vast tundra of North Yorkshire, UK ). We are in the little seaside resort of Filey.    We supply internationally too and you can choose at checkout  to pay in ÂŁ, € and US $, Shekels, Zlotties, Australian $, Norwegian crowns, and other currencies.  Everybody is welcome.
