Re: Help required finding a Tek 466 power rail short

You probably do want to up the wattage on that bulb. I've got a board with 5 bulb holders on wired as a dim-bulb tester, so I can play tunes (up to 5 * 200W bulbs if I can find any).

Through the dimbulb tester (which also passes a voltage regulator) the line voltage is exactly 116v. According to the manual, the 'Hi' selection works from 108v to 132v, so I believe it should be ok? I only built the dimbulb tester for this repair, so have next to no experience regarding their use. I have wondered whether the 220v 60W bulb is the wrong value on a 127v supply and a 100W appliance? |
