I can always fit an International Octal base in place of the Mazda one for the detector if needed.
It has been my finding that the type of valve in the anode-bend detector does not seem to be ultra critical.
I bought the SP61's by mistake when I had a genuine Premier kit TRF. That had a VR116 as detector, equivalent to a 6.F.32. Both sorts seemed to work OK. Usually you see a 6K7/EF39 or 6J7.
