JENA has worked very hard in having as few Chinese parts or Components as humanly possible, for many years now.
     The reason is independence and liberty as an integral part of American made products. 
 We do not depend on C.C.P. favor, approval or permission to make the very best we can...
AND keep the products great by not using junk.

  The Sequoia-Seedling and the Twig based on the primary input of the Sequoia AC Power Conditioner - Just received,     The Prestigious Brutus Award ... from Positive-Feedback online Magazine - We are quite proud of that and speaks to the superlative performance of our designs.

        who we are© Updated  Feb 19 th  2021  some site resetting links and structural form in progress...

                Designed and Manufactured in the United States of America with pride and accomplishment.

            We are experiencing the results of power outages and the freeze of winter in 2021.
                Shipments are being delayed due to weather... we apologize... however it is the shippers, are having trouble due to weather conditions. 

                We had a blackout of 5 days were all power was not available and all communication was out - back online now :) 
                    Our efforts are set to being productive no matter what the circumstances are...  
                        Liberty and Freedom for all, or none have either.
