Albert Porter Technics SP10 MK3 Project

Description

This is a project that's been on going since the days of my Lenco experiments. My Lenco project is posted as a virtual system here at Audiogon too.

My Technics SP10 MK2 in custom African Wenge plinth is posted in my main system and this Technics SP10 MK3 in Panzerholz and Ebony Plinth was completed November 20th, 2008.

More images to follow, including the Ebony custom platform it will rest on. The platform is 9 layer construction including a layer of Texas Instruments shield with active ground plane.

On page two of this document there is a list materials showing their specific damping capacity. Iron was chosen for Albert's plinth because manganese bronze was prohibitively expensive and the magnesium alloys weren't readily available. You could say that grey cast iron offers the most damping capacity per dollar.
