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.
Groove tubes were founded back in 1979 by Aspen Pittman and have become
one of the most respected valve brands in the world.
We Offer The best tested Groove Tube valves in the world
We take selected GT items and in addition to GTs in house testing and distortion rating on output valves they also undergo our own unique real world burst testing. The burst testing process involves a series of varying timed electrical signal bursts. This runs the valves under the same stress conditions that they will meet in your amplifier. All output valves are then dual matched by us on current and gain. This will ensure that you get the best selected GT valves available anywhere in the world.
We believe this combination gives you the best tested valves available anywhere in the world.
