About Us


We are located in Arlington Heights IL, a northern suburb of Chicago, 15 minutes from O'Hare Int. airport. We have been in business since 1958, originally selling radio and TV parts and accessories to service dealers and retail operations, then branching into some industrial electronics. As the radio and TV business wound down we expanded our A/V supplies and became heavily involved in home theater, structured wiring, home automation, lighting controls and associated electronic parts and accessories.
We have a large, attractive showroom to display all of our products where you can touch, feel, and make decisions. If you are in the area, we welcome you to visit. If that's not possible, please order on our secure website, where we ship 99% of the orders received the same day when placed by 2pm central time.
As an authorized distributor for all the products we sell, all items purchased through us are supported by both tselectronic.com and the manufacturers warranty.


Customer Comments

"My Belden 7915A cable was waiting on my doorstep last night when I got home, earlier than expected. I appreciate your good service."

"Because of your excellent prices, I took a chance by placing and order with you. I'm very glad I did, because the service I received was excellent."

"Greetings. i just wanted to take a moment to thank you all for the excellent service (once again). in these times of less for more, one thing that can stand out is customer service. i find your website easy to navigate, your inventory rarely disappoints me, the (real human) advice helpful and as above, ordering and shipping excellent."

"Thanks, you people have been great to deal with. Thanks again."

"You guys are doing a great job, everything we order is always prompt and correct"

"I ordered some coax cables and connectors to rewire my house. After placing the order, I received a call from Tri-State asking me if I meant to order the connectors I did because they were not compatible with the type of cable I ordered. After telling him I wasn't sure, he informed of the correct ones to purchase and changed my order to reflect it.
I've never had someone call me like that to make sure I was ordering the right thing. I've also never felt compelled to go online to give a review of a site, but I was so impressed and grateful that they did this for me; I wanted to return the favor in some way. So, I give this site a big two thumbs up and will definitely use them again."

"We received the order yesterday. Thank you for expediting this. We appreciate the great service. Have a great day!"
