Smaller and lighter tonearm developped after the original PUA-9, available separately for 30,000¥ but mainly sold as mounted on the PS-X70, PS-X60 and PS-X50 bestsellers.
Released after the PUA-1600L and PUA-1600S, the july 1978 standalone version of the PUA-7 is extremely rare - a proof of people's latent snobism :-)
• Arm wand is made from high tensile aluminium pipe with diameter 10mm. This material has 8 times higher flexural rigidity than conventional material (in our company). This makes for low resonance and good balanced sound.
• Heavy brass arm base supports arm rigidly.
• Polyurethane covered Litz wires are used for lead wire & phono cord. This reduces transmission loss due to high impedance. Terminals are gold-plated for anti-corrosive and low resistance characteristic.
• Special SH-165 head shell is made of aluminum clad with carbon fibres. This has high flexural rigidity for low resonance.
• Inside force canceller by combination of special cam and spring can compensate side thrust of arm exactly.
• One-touch arm height adjusting mechanism without step between +/-3mm.
