FYI, I just got a notice (and then placed an order) that AMR are doing another run of SVX radiators (they say 30 units). Link here:

AMR did a batch in mid-2018, and I didn't hear anything negative, although I know they've had unhappy customers in the past. Personally I've had a relatively positive experience dealing with AMR in the past (buying a set of coil overs from them).
Cheers,
Ian.
