Collectability

Many of the Earth Sound Research amplifiers are considered rarities throughout the vintage amplification world and are collected by many vintage amplifier enthusiasts.


Design infringement

Most of their models were either outright or close copies of then current, successful amplifiers and other audio equipment. Early Earth Sound Research amplifiers used all tube circuitry and were assembled inside the Benjamin Electric Sound plant in Farmingdale. The company also hired subcontractors for component assembly. Qualtrol Electronics, Inc., a third party subcontractor located in Deer Park, New York, supplied Earth Sound Research with amplifier chassis and sub-assemblies. Andy Fuchs, a former employee of Qualtrol said “I worked for Qualtrol, the subcontractor who made the

clones... Qualtrol did a nice job (in my opinion) of copying the Peavey gear (for Earth Sound Research)... They (Qualtrol) cloned the circuits, which (ironically) were RCA textbook Transistor Manual circuits.”


Reason for failure

According to Gabe Dellevigne, who has researched the Earth Sound Research brand, "Peavey was very aware that Earth had been stealing their designs and repackaging them as their own products... the demise of ESR was not caused by any form of litigation or infringement proceedings, rather, they simply folded for financial reasons as so many other short-lived instrument amplification companies have over the years.”
