  • Notes

  • This Orion Micro Seven radio model uses an almost identical chassis as seen in the Orion 7TR, and has a similar circuit design as seen in other models from different brands such as the Standard Micronic SR-G430, where a transformer-less push-pull output stage directly drives a special high impedance center tap speaker. In this model the speaker has 60 ohm impedance CT.
