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.
Watford Valves have been supplying specially tested valves for Mesa Boogie amplifiers for over 25 years. To help you maintain the sound we have now put a picture of the original factory item next to the Mesa label item to help you identify the valves in your Mesa.
Mesa normally gave a separate STR number to each valve which would normally indicate a different factory. Recently Mesa have given the same STR numbering to valves from different factories. To aid your identification we have given the valve a type number, type 1 type 2 etc.
What makes WV Mesa Select valve ?
Our matching process as stringent if not more so with valves matched on plus-or-minus 2 mA of current. Just like Mesa, valves that will reduce power or not be within the range of your amps optimum performance will not make the grade. Just like all Harma output valves our Mesa select valves 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.
We have spent over 25 years helping Mesa owners maintain their amps factory sound without compromise on testing and selection.
