[TenTec] 238 "Tuner" Balun

[Bob Good]

The Ten Tec manual has virtually nothing to describe the internal balun supplied with the unit.  I do not know how to physically look to tell its design.  Is it a 1 to 1 or a 4 to 1;  Current or Voltage design?  Okay, if it is 4:1 or voltage design, please comment on the proper  design in schematic form or picture; what ever it takes for me to wind a current design, 1 to 1 balun.  Can the toroid be reused?  I use it on a ladder line, center fed 135 ft. dipole up 60 ft.  Other antennas are coax fed.  Thanks to all who would like to help this analog old timer.  Happy New Year and ‘73.  Bob K4BG.
