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.
The Mesa 5Y3GT Type 2 is the JJ 5Y3GTS which Mesa sourced in recent years from the JJ factory in Slovakia. This valve can be identified by the rectifiers rounded top, anode plate structure and star ends to the top mica and we call it type 2.Mesa normally gave a separate STR number to each valve which would normally indicate a different factory.
