Mas isso é uma coisa que faz parte da maioria das células mono , recentes e não só, a minha SPU-A de mil novecentos e trócopasso já é assim...
Mas sim, há células mono só com dois pinos, como a denon dl103 mono

A tua célula SPU -A tem uma agulha de 1 mil indicada apenas  para os grooves dos discos monos antigos feitos com laquers mono.

Esta Ortofon Mono tem uma agulha .7 Mil apropriada para os novos monos feitos com laquers stereo ( Beatles mono) mas também pode ser usada com os discos monos antigos.

Por exemplo as recentes Miyajima mono tem todas agulhas 1 Mil.

A explicação dos dois pinos é por ser uma célula MM no entanto a junção foi bastante "inteligente"... Vê só a explicação que a Ortofon dá;


Here is what designer Leif Johannsen writes about the Ortofon lineup: SPU CG: The old 1948-design with only lateral compliance and one coil SPU Mono, Cadenza Mono, Quintet Mono: Both lateral and vertical compliance and one coil. The armature has been turned 45 degrees from the stereo-position. 2M Mono and 2M Mono SE: In the MM we cannot turn the armature or anything else. So the mechanical geometry is the same as in the stereo 2M’s. But we can couple the two coils in a clever way (NOT simply parallel between L and R)) and thereby making it work as one coil. The point is to have a design not sensitive to vertical movements and that has been achieved.

The key issue for mono playback is not the number of signal coils - but their angular orientation, which determines whether they are sensitive to vertical groove modulations or not. A coil design that does not pick up any vertical modulation in the first place gives better sound than picking up the vertical modulation, then attempting to cancel it out later.


IME, what works best in a normal stereo system, is a cartridge with two mono coils. This eliminates any sensitivity to vertical groove modulations, yet avoids the hum issues that a single-coil cartridge may be prone to
