Hi my EAR MC4 has 4 taps I think it fits your description. Here's a good review btw ...and covers the various gain/loading options...

It's worked very nicely for me...and my Lyra at .54 mv and the Allaerts at .2mv..
I am actually thinking of trying a different SUT...maybe one the Ypsilon's...no real reason other than experimentation...possibly the Allnic SUT also..
Curious what others come back with here...
