So just to keep you all hanging on I can report that the Malachite body is now at NWA and Dom is going to do a total rebuild on my 103 including coil rewind, DMC cantilever and FG stylus. This will turn it into what he terms a NWA DL103.
I have to say the service from NWA is outstanding. Natalie is fantastic at logistics and communication. If the after sales service is as good as the pre sales service (and I am sure it will be) NWA is that rare breed that combines technical excellence with professional, responsive customer service.
