Description: Features: two in the standard circuit; In the middle of the week has been adjusted in the 465KHz Shell plastic as a new material, never to return. Circuit at all levels have Ic test port. Circuit diagram, assembly drawings, and other parts of the list, complete technical documents. Volume: 115 x 65 x 25 Frequency range: 525-1605KHz Output power: 100MW Power supply: 3V (No. 5 battery) (optional) Circuit theory introduction: the main properties of the 108-2 7 transistor radio frequency range: 525~1605KHZ; output power: 100MW (max); speaker: 57mm diameter, 8 ohm; power: 3V (No. 5 batteries second section); volume: 122 x 66 x 26. As shown in Figure 2.1 the electrical principle diagram. Seen from the figure, the whole machine contains 7 transistors, so called 7 tube radio. Among them, a triode V1 for converter tube, V2, V3 is in the discharge pipe, V4 detector tube, V5 for low frequency amplifying tube, V6, V7 for low frequency power amplifier tube. This kit does not contain a battery Package Includes: 1 Set electronic parts of seven tube radio
