AR 3a improved crossover schematic


Recommended Posts

Hi guys,

There is anyone knowing the crossover schematic for an AR 3a-improved of 1977? Those having no more potentiometers, but only a 2-positions switch.

It would be well different from those well known of AR3 and 3a still publicized in this site.

Can you post it here? Any form would be welcome, also hand made copied ones.
