About Us - Who we are and what we do...

Electro-Stock, Inc., formerly CS Technical Sales, Inc., an Illinois Corporation, celebrating our 31st year, has been in business since August 16, 1983. Dennis Chadra and Glenn Schilke initially started the business under the name of Chadra-Schilke & Associates, Inc. As a manufacturers representative firm for several manufacturers of electronic components & controls we sold to an exclusive territory on a commission basis. The contracted territory covered northern Illinois and eastern Wisconsin in which we sold to the OEM market.

On our 10th anniversary in August of 1993 we started a distribution division. Selling under the name “doing business as” CST Electro-Stock. We stocked and sold electronic components and controls which complemented but did not compete or conflict with the lines represented.

We ceased our manufacturer’s representative activities in late fall of 1996 allowing us to direct all of our resources into the distribution business selling nationally. In order to separate totally from the representative business we once again changed our d/b/a name to Electro-Stock, Inc.

On August 16, 1997 Dennis Chadra accumulated 100% of the shares of the Corporation and Glen Schilke left the company. Russell Chadra was appointed Vice President and at the annual board meeting a Resolution to amend the Articles of Incorporation changing the name to Electro-Stock, Inc. was adopted and submitted to the State of Illinois.

We maintain the policy of keeping the lines as compatible as possible for maximum account penetration. Our mix of custom and off the shelf products gives us a lot of flexibility in offerings.
