Re: replacing tuner needle indicator bulb

i have worked on some yamaha's, and believe you need to remove the bracket off the top of the needle. Also be careful as some of the yamaha's use 24v bulbs

Re: replacing tuner needle indicator bulb

you are correct i figured it out found lamps at frys they are 14.5 volts 80 ma which i have read are not the norm for yamaha

Re: replacing tuner needle indicator bulb

Yes now I remember that a lot of yamaha's use the 14v bulbs and connect them in series pairs, when wiring on the power supply board. If you have 1 open bulb and you measure across that bulb, it will show 24v to 28v. but in reality this tells you the other bulb is good. Before dismantling the pointer assembly you may want to ohm out the needle bulb to make sure it is bad, and not its 14v series pair.
But I have also found "both" bulbs in the pair open as well. I have used 14v Green LED's for the multiple twin lead lamps in yamahas rather than "bulbs" because they last longer, and draw less current. If you can only get 12v types, you may need to add a series resistor on the leds's to keep them from getting too hot.
