1. [TenTec] 238 "Tuner" Balun (score: 1): Author: "Bob Good" <k4bg@planters.net>; Date: Wed, 27 Dec 2017 21:10:48 -0500; 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; /archives//html/TenTec/2017-12/msg00067.html (7,581 bytes)

I will assume you are speaking of the Model 238-x range of matchboxes. They all have a 4:1 Voltage balun which is more or les; /archives//html/TenTec/2017-12/msg00069.html (12,782 bytes)

I use my TT238 tuner with an external 1:1 current balun comprising 11 turns on two stacked FT; /archives//html/TenTec/2017-12/msg00070.html (10,155 bytes)
