Still, there are lamps on the market that look although they have filaments but are actually LEDs. So maybe there will be convergence... Mike. |

Yep, it's open. I measured the resistance on the pot in the dead modem, which appears to have a good pot. 10K ohms across the outer terminals (in circuit), and the center (wiper) varies when turned (like it should). When I measure across the outer terminals on the modem with no sound, it's infinate resistance. The pot has a metal housing around it, so I cant see what is goingv on inside, but there must be a crack of sorts. If 10K is what it is. I'll clip a 5K resistor in there That shoujld give half volume.If that sounds right, I'll jusat tack that resistor in it. |

Another thing you apparently can't understand. If the screws rust, the rust embeds itself in the plastic. -- Jeff-1.0 wa6fwi http://www.foxsmercantile.com |
