What is Codan 9350 Autotuner's Series?
See:
Series A - orginal motor coupling made of silicon rubber. Softened on contact with the silicone grease used to lubricate the leadscrew.
Series B - New black plastic motor coupling. Was found to be brittle and liable to breakage from impacts. Not many made, even fewer surviving.
Series C - Motor coupling returns to silicon rubber, reinforced with spring clips. Leadscrew now lubed with dry graphite to avoid previous failure mode.
Series D - Contact spring riveted at one end to the tuning slug. Eliminated noise problems with dirty coils/conductors.
Series E - improved strength to top cap fixing.
