Trompeter Technical Notes are issued papers written by the Technical Support Department on matters that concern our product line. The subject can range from new product updates, the existing product line, tooling, or any other item of interest. Typically, through customer calls, the Technical Support Department may see a need to create a Tech Note on a specific subject. Ideas for the Tech Notes also come from Trompeter's inside and outside sales force, marketing and engineering departments. We hope that these Tech Notes are informative and if you have an idea for a Tech Note, please feel free to send your suggestion to the Technical Support Manager techsupport@trompeter.com. Thank you.
