Sony VFET PCBs are now available for purchase separately. The VFETs themselves are not available for individual sale - please see this post on diyAudio for more information or to join the waiting list for the next batch of VFET kits to be made available.
Pairs of the UMS compatible TO3 brackets we had made for the VFET kit are now available for individual sale. These are (currently) stored in our USA warehouse and (currently) ship from the US.
