High Performance Stereo is pleased to announce that the Marine Corps Heritage Foundation in partnership with the National Museum of the Marine Corps in Triangle, VA, located near the Marine Corps Base Quantico, has selected the HPS-4000® sound system for the new large screen theatre currently under construction.
The theatre will boast an 80 foot wide screen that is also 60 feet tall and will be the home of a special new large format film now in production.
The EIA assigns each manufacturer a three-digit code (there are some with one, two or four digits).
When dating an instrument by the ‘pot code,’ keep two things in mind: The potentiometers must be original to the piece (new solder, or a date code that is off by ten or more years is a good giveaway to spot replacement pots); and the pot code only indicates when the potentiometer was manufactured!
If the pot is an original, it indicates a date before which the guitar could not have been built – so it’s always a good idea to have extra reference material around.
Finally, a word of caution: This method applies only to American made pots and not all potentiometer manufacturers subscribed to the EIA source code date.Get dating advice and anecdotes from our very own Match bloggers on all things relationships!Our writers explore and prepare you for the thoughts and feelings we all experience on our dating journey to keep things fun and interesting.Stamped on every potentiometer (volume and tone pots) is a six- or seven-digit source code that tells who made the pot, as well as the week and the year.The source dating code is an element of standardization that is administered by the Electronics Industries Alliance (EIA).All retail consumers should contact your Eminence supplier for warranty and service information.
