We can repair most Ten-Tec models. We are doing component level repair on older models and do not have replacement circuit boards. Although we can repair most older models, the repair cost can exceed the value of the product. Some products are not fully repairable because of the unavailability of components, these include:

444 Hercules Amplifier: final transistors and many other critical components and mechanical parts are no longer available. The 444 is generally not repairable.

535 Argonaut II and 536 Delta II: Backlight for display is no longer available, otherwise repairable.

Effective February 15th 2015 service department labor rate will be $110.00 per hour. 

Turn around time for non-warranty repair is generally 2-4 weeks or less depending on workload.

We will mail an invoice or email charges after the repair is complete. You may pay by credit card (Visa, Master Card, Discover or American Express), personal check or money order.
