There are a few balanced tuners available for purchase. I assume you
just want the building experience? If not, Johnson Matchbox tuners are
sometimes available on Ebay and other sites. And MFJ has two current
models. And Palstar has one current balanced tuner.

Good luck, jimbo

Any
ideas and thanks in advance.
