Happy to report that the Roksan is work ng extremely well. I drew up various templates and made an armboard from MDF. I had to route out the unerside to accommodate the 32mm AF mounting nut as it fouled on edges of SME cut out. Also had to remove the plastic surround int the turntable arm "recess". The Bias control sits 45mm out and just clears the top plate. I will get some photos. I tidied up the turntable; level, foam in the springs, earth tags, bearing oil, motor rubber mounts and made sure it was isolated.
I will get some pics later.
Needless to say it sounds fantastic.
STD turntable, Roksan arm, Goldring G1042 cartridge (properly aligned), Cambridge Audio preamp, Yamaha RX-AS710 amp and Spendor Prelude speakers (old but still fab)
The arm was a bargain and immaculate.
