@saulh Congratulation on your venture into Vintage Japanese DD TT's.
I recall quite well the period of time I purchased my first one, I travelled nearly 400 miles as a round trip to purchase it, and then another couple of hundred mile round trips to and from the premises of the Engineer that was to breathe their magic onto it.
I was patiently sitting the time out, awaiting for the call to inform that my first purchased model, was to be released from the Technician/Engineer who was overhauling it to their specification.
