A Burns Buzzaround type circuit with some (pretty rare) Phillips OC75 metal can transistors.
The finishes on this batch of Omolon's are all custom airbrushed and highly polished. No two are exactly the same but there are more than one of each colour. The circuits, transistors, tuning etc is the same, just the finishes that differ.
Unlike the earlier White versions these units also incorporate a DC jack and LED.
