It is with some regret, we have decided to stop selling New ‘Old Stock’ tubes via our webstore.  Supply of good tubes is becoming limited and we are now focussing our resources on the Great British Valve Project and our existing product range.  We will continue to take the remainder of our NOS tubes to specialist shows like the NVCF until the remaining stock is depleted.  Thank you to all our NOS customers over the years and we hope that we can persuade you to migrate to our new manufacture valves / tubes.
