We are a group of hands-on engineers with a keen interest in vintage audio and mechanical devices. We design and offer a variety of vintage and modern audio related products to the audio community. 

We believe functionality, durability, ease of use and product appearance are integral components for engineering design of audio products.   These key attributes, along with customer service, are the key to our success.  As a US company, we employ very strict testing and quality control procedures for all products that we offer. 

In addition to our design workshop, our test facilities house various types of audio test equipment.  Additional facilities include various US made tube testers (Amplitrex and Hickok), along with several custom-built tube testers that we use to evaluate the quality of vintage US and Russian vacuum tubes.
