 Hi to everybody. I have the Lundahl LL1931 transformers that I need to wire for the 8:1 step up. The diagram from Lundahl has me a bit confused and I'll admit this will be my first attempt at something like this. Can someone help out with a better wiring diagram or instructions ? It will be conventional RCA plugs from the cartridge and RCA plugs to my phono preamp. Thanks all, Will

 Look at the datasheet link, where there is a diagram for wiring.

 I have that data sheet but out of the three boxes at the bottom showing different grounding schemes I'm just not sure which one to use. Thanks, Will ps like I said I'm kind of wading through new territory here, thanks for your patience !

 Will,

Yes those descriptions can be a bit tough to follow if you aren't aware of where your tonearm cable and phono preamp input fit into the alternatives described.

I am a bad typist, so we can get farther faster on the phone. See my webpage at http://www.kandkaudio.com/ordering/ I answer from 8:30 AM to 5PM EDT.
