i have this radio the lamp went out in it it takes a 12 volt o. 15 amp ihad to get a 14 volt 200 ma lamp part number 1815 it has two white wires cming from it where where do i solder the wires to the bottom of the lamp and melt wax and put around it that what the old one had i took the old lamp apart it looked like it had two wires coming out each side real small that the wires was soldered to

Your post is difficult to follow but it sounds like what you are trying to do is replace one of the wire-leaded subminiature lamps that the Japanese were so fond of putting in their audio equipment for VU meter or tuning dial illumination. The thing that I've found that works well as a replacement is a "grain of wheat" bulb. These bulbs come in different voltages around 12 V, have wire leads several inches long, and are sold in hobby shops that pander to model railroaders and/or dollhouse miniaturists. They are also readily available via e-tail from most online hobby stores.

Just solder the ends of the two wires of the new bulb to the same tie points or feed wires as the original lamp. Then stick the new lamp into whatever backlight cavity from which you pulled the original and secure it with a small dab of clear silicone adhesive. Fire it up and adjust the lamp positioning to give even illumination before the silicone sets up.

CV,

I'm probably all wet on this, but what he explains probably is a repair to get light back in the unit. The repairman probably did not have a fuse type cartridge lamp so just soldered in a lamp with leads on it.

I can't tell. The STA-20 is a low-powered tuner/amp, intended to be part of an "entry level" component stereo setup. I last owned a Realistic tuner/amp 30+ years ago (as I recall, it was a very nice-sounding radio, although only about 20 watts/channel output). It had hardwired, "non-user-serviceable" lamps in the main sliderule dial and the VU meters. One of the VU meter's lamps quit working several years after I bought the unit, and I was able to replace it with a "hobby lamp" as I described. These little lamps are still being sold, although LEDs are gradually displacing them.
