Yeah, if you get the LM1875s with the plain metal tab, you'll need a mica as the tab is connected to B-. There are some LM1875s that come with insulated tabs, but if I remember correctly, the insulation on the tabs doesn't conduct heat as well as a mica....

The project got stepped on by other higher priorities
Actually working hard on CAF 2017 already, really pushing hard on getting the show sold. I have a few of the large rooms sold and a couple of smaller listening rooms done

How is the new house doing.
I saw Mike Rafferty recently and his new house is being built near your old house.
So you used to be neighbors in the future
