well my personal interest started from explorations into MM carts with the conclusion that almost none of the commercial solutions are fit for purpose. Holman was onto something back in the 70s. For MM you can make a very cheap phantom powered headamp that you can put inside the turntable. Worth knocking up for a bit of fun*. Plus the look of horror on audiophiles faces when you mention phantom power and Vinyl in the same sentence :).

*Other's definition of fun may vary. Not sure JR can have fun unless an angle grinder is involved these days :P
I enjoy reengineering my solar lamps

I wanted to let our readers know that the ZTX851-based moving coil preamp board will be available for purchase in about 10 days.

The initial prototype run sold out and I've ordered production quantities.

Construction information, a bill-of-materials and circuit description are available in the "Build" section of the forum. viewtopic.php?f=7&t=1179
