This is essentially a proof of concept. In order to complete it I bought a metal lathe and a sandblaster. Luckily I already had the copper plating setup and know someone who is OK at winding transformers. The end result is a pair of very well shielded 1:20 SUT's for an Ortophon A90. Dimensions are 4" X 7"
