I found a SKA PRE/OptiVol kit I knew I had somewhere and a Plitron 077017201 300VA 2X115 Input 2X30 VAC Output toroid. Both new and unused but I did start the SKA PRE when I bought it and a few resisters are installed.
$50. plus shipping for the SKA PRE.
$50. Plush shipping for the Plitron transformer.
