LONDON Decca, Tzar DST and similar cartridges

@halcro - hi, I’m just trying my LDR at 1.65gm with minimum bias on FR66s. I tried it last night and it was very nice at that setting , will have another go later...
I asked John Wright what the VTF should be and he said “1.8gm +/- 0.2gm” so I guess the recommended range is 1.6-2.0 gm.

@howardalex, a while ago there was some talk on this forum about 'special' FR7's with unbelievable specs. Very rare and perhaps aimed at the professional market, as you suggest. In any case, it appears you are in possession of something truly special! 
The FZ version is usually quoted as the best of the regular models, but I have come to prefer the MC 702. Another peculiar and rare one, apparently the last of the FR7's and supposedly aimed at the European market. Whatever the case may be, it is exquisite.

I’ve now listened to the LDR at 1.65 gms and on some of my (admittedly quite worn) 1960s Argo recordings there was some mistracking, so I’ve increased to 1.85 gm which seems to banish that 

Thank you @halcro beautiful song :) ! Cannot judge the sound on this one as I'm not listening pop/rock so no points of reference. Thank you also for the VTF setting, will try that!

HowardAlex, my tonearm must be better!
