Dr. Jerry Sevick, W2FMI, in his years of research has wound over 1000 BALUN and UNUN transformers and has used over 1 mile of wire over a 20 year period. The results of his sensational work are the powerful 2kW to 10kW, 98% efficient 1 MHz to 50MHz BALUNs and UNUNs. This work is featured in over 20 articles, 3 books and this website.

Another result of this work is hundreds of wound BALUN and UNUN transformers that Dr. Sevick would like to liquidate. For a limited time, you can get a hand-made BALUN or UNUN transformer, built by Dr. Sevick himself. These carefully crafted transformers were constructed for testing and study purposes during the course of Dr. Sevicks investigation into the theory and practical applications of Transmission Line Transformers.

Each transformer comes with a detailed description of its design, what it would be used for and how it was constructed. The unit will be accompanied by a certificate noting its authenticity, signed by Dr. Sevick.

These transformers are available for $30 (plus postage) until they are gone. We cannot honor requests for specific designs, units will be shipped on a firsTcome firsTserved basis.
