I did not open it, but saw internet pics of the interior. Beautiful, well made tuner. The dual roller inductors were impressive.

W3SLK: Try Rich Measures Balanced Balance Line tuner. K1JJ: Fred, Good to hear you're concerned about unintentional tuning up QRM to the QSO. The linear Q is low enuff that you can easily go down the band 20kc and find a clear freq to tune up. The peak tuning will be about the same on the QSO freq. I can QSY -+40kc w/o retuning my linear tank. The input coil connects to your radio and the big coil will have to be tapped out to match the aerial to the radio system. I had a vacuum variable cap available and that connects across the entire big coil. You can SEARCH for the K1JJ tuner and you will see endless postings.

Also see antenna tuners . I never really used link coupling very much. My very first transmitter, and all transmitters after that, used pi networks.

That said, most of my modern class C or linear builds now use a reverse pi-network for the input. You can get it to tune and work well from 10-160M easily.
