Great communication, good shipping and nice packing. This is the place to obtain Lundahl transformers in the US.

I installed a HV Shunt Regulator In my Counterpoint SA-3 and the improvement is dramatic, removing another veil. Very fast and clean with improved transients, and incredible bass. The kit and documentation are first class and it worked straight away.
