Watford Valves have been using valve equipment since 1976 and has been selecting and supplying valve to the professional market for over 20 years. The term 'new old stock' refers to tubes or valves which are new but are from factories which have long closed down. These factories such as Mullard, G.E.C, Telefunken, Siemens, Philips, General Electric and R.C.A produced some of the best valves ever made which is why these items have become very sought after in the music industry. Watford Valves keeps a huge inventory of new old stock tubes valves as well as current production items. Therefore Watford Valves can offer one stop shopping to satisfy the most demanding of needs of the professional market, the collector or the enthusiast. All output tubes valves are priced individually. All prices contained on this web site are exclusive of VAT.
