The TS-120V is equipped with a two bulb lightshow. Remember that the chassis really warms up above the VFO-scale and the S-meter...
I replaced the two bulbs with green ultra-bright LEDs and matching resistors in series. The resistors give you a chance to adjust a pleasant illumination level (I always felt the lightbulbs beeing to bright). As standart
LEDs are a little thicker than the original Kenwood bulbs one need to cut off a part of the VFO-scale lighting rubber mounting sleeve's rear portion. Cut of the bulb's wires close to the glas body, they will perfectly serve the new LED-R combinations.
Experience:
- RX current went down by 300mA
- scales do not dazzle anymore in a darker shack
- chassis does not heat up as fast as before
(still some heat above the frequency counter)
- => less VFO drift than before
I will not sign responsible for any damage produced with this modification!
