Highlights & Features of this tuner:
The twin inductor/current balun design provides a truly balanced
output.
(2) 14 uH roller inductors, coupled to a WW II vintage dial with 25
turns, 1/100 turn markings.
High/Low Impedance Switching: Switches the capacitor bank to
tuner's input or output. "HI" position is used for impedances above
50 ohms; "LO" is used for impedances below 50 ohms.
Variable and fixed capacitance controls - continuous range is from 25
to 1250pf @ 4500 Vpk.
Variable capacitor dial is the classic 4-inch National Velvet Vernier.
Beautiful, real wood venier over aluminum front panel.
In Photo 1, the large coil on the right is a coaxial choke balun that
goes between the output of the rig and the input of the tuner. Please
indicate if you do not plan to use this coil, I will be happy to
install a ferrite choke balun inside the cabinet.
Dimensions: H,W,D = 8 X 19 x 15 inches, approximate weight = 30 lbs
Good luck with the bidding,
