[TenTec] TenTec Digest, Vol 168, Issue 1

[Edward McCann]

Denton- 

Concur fully with your observation that Voltage Balun does not CMC suppression.

My question trying to ask if the early TenTec tuners used a Voltage Balun (as did most the early Heathkit, Dentron, etc. tuners of the day) to provide balanced output, OR did TenTec supply in its 229A series a Current Balun, with its better CMC suppression characteristics.

The question could have been phrased using more concise use of the English language.

Rick DJ0IP,  advises re the 229A that:

" In this case the 4:1 [in the 229A tuner] may be a voltage balun.  Its only job is the impedance transformation."

When the thing gets here (just purchased on 2nd hand market, and not yet arrived at this QTH) I guess I'll just open it up an look. 

Rick's comments are spot on with regard to the world of Baluns in general. 

But thank you both.
