I'm looking for plans to build a balanced tuner for ladderline without a

inductors. Can't seem to stumble back upon these on a web search. Any
ideas and thanks in advance.

Hi Gary,

you may find the following web sites of interest in designing your own
balanced tuner.
hope they help in your quest.

another approach is the Z-Match tuner

(Note it is very desirable on the Z-Match to have Vernier dials as the
Adjustments can be very sharp and easy to miss without them.)
