Cadmium has been out of use in dangerous form for a long many years now... decades even. Decades, eh? Guess the median age of the equipment we work on in AGA... Nickel Cadmium, a typical electronics plating media, is NOT one of the dangerous types, and is likely the most common you'll see in older equipment. The dangerous uses have indeed been out for a long time, and the places where more pure bits of cadmium were used is not likely in the gear you refer to. Certainly not on its exterior. |

I must say, I *rarely* work on the exterior of a 50 year old guitar amp... mostly, I'd be inside it. What is that yellow fuzz growing on the speaker nuts of my '61 Gibson Falcon? Tasted funny, anyway... I hear Hammond organs are plagued by 'cadmium fingers'... you have to zap them when they short out key contacts. __ Steve .. |

Gave us: I must say, I *rarely* work on the exterior of a 50 year old guitar amp... mostly, I'd be inside it. Figures you'd **** up a perfectly good antique by thinking that working on it "fixes it". Yeah... you fixed it alright. It is worth one tenth what it would have been. What is that yellow fuzz growing on the speaker nuts of my '61 Gibson Falcon? Likely cigarette tars. You're too ****ed in the head for it to be cannabis tars. Tasted funny, anyway... Must not have been Cadmium then, or you would be in a world of ****, dip****. I hear Hammond organs are plagued by 'cadmium fingers'... you have to zap them when they short out key contacts. Do you know ANYTHING about reed type contacts? Anyone with any brains would switch them out for platinum points, and a low voltage circuit that fires SCRs or the like in place of that ****. Guess what... no more "fingers" of any kind. Such knowledge comes from a few years of working on old style pinball machines, and then on modern version where the voltages presented to the contacts are low, and the currents are as well. Pinball mean life between servicing PMLBS goes way up by a factor of five or more. I guess your funny tasting tongue just got its fingers zapped. Just so you know, I never said a goddamned thing about it having been banned that far back. Stop adding cross posted groups, Usenet ****tard. |

Figures you'd **** up a perfectly good antique by thinking that working on it "fixes it". Yeah... you fixed it alright. It is worth one tenth what it would have been. Curious person, this MassivePrawn... not sure if there's a brain working in there, but it *does* write English, after a fashion... just fyi, if we don't fix the antique, it stays broken. Same for you? What is that yellow fuzz growing on the speaker nuts of my '61 Gibson Falcon? Likely cigarette tars. You're too ****ed in the head for it to be cannabis tars. Anyone else not getting sense out of this? Tasted funny, anyway... Must not have been Cadmium then, or you would be in a world of ****, dip****. Irony is lost on it... I hear Hammond organs are plagued by 'cadmium fingers'... you have to zap them when they short out key contacts. Do you know ANYTHING about reed type contacts? We'll see... Anyone with any brains would switch them out for platinum points, and a low voltage circuit that fires SCRs or the like in place of that ****. Guess what... no more "fingers" of any kind. well, yes, as you point out, I *do* know a thing or three about contacts, both leaf and reed. Have *you* ever had your hands inside a Hammond Organ? Do you have any idea how many contacts are made with each key closure? And why "**** up a perfectly good antique " by ripping the heart and soul out of it to replace each key contact set (14, is it) with SCRs... let's see, 14x61x2 (great and swell)... 1708 SCRs. Ludicrous. Such knowledge comes from a few years of working on old style pinball machines, and then on modern version where the voltages presented to the contacts are low, and the currents are as well. Pinball mean life between servicing PMLBS goes way up by a factor of five or more. You play pinball, and I'll play music. Appropriate, eh? I'll let you play my old Gottleib... I guess your funny tasting tongue just got its fingers zapped. As I said, Irony Lost... Milton's other masterpiece. Just so you know, I never said a goddamned thing about it having been banned that far back. See this? : / This is my Don't Give A **** face. Stop adding cross posted groups, Usenet ****tard. Haven't touched the Newsgroups: line, myself. __ Steve .. |

I used to have a Baldwin, once... left it at the dump, no usable stuff inside. I suppose you're the one that invented those silicon contacts? The ones that are unobtainable, and render the unit unrepairable (thank god, anyway!). __ Steve .. |

Ludicrous. You obviously have no clue as to the form factors available. Also, if you are having your "Cadmium fingers", the ****ing thing doesn't function properly to begin with. Simply switching to platinum contacts would solve it without the switch to a low voltage design. If these are antiques, what's a retard like you doing opening them up anyway, dip****? You have all the capability of a freshly laid turd. |

Ludicrous. You obviously have no clue as to the form factors available. I don't care if you put 300 of them in a package, you still have to connect them. Still doesn't change the requirement for 1700 some-odd devices. Also, if you are having your "Cadmium fingers", the ****ing thing doesn't function properly to begin with. Actually, the circuit is so low impedance that it *will* function with some shorting going on... we installed the TrekII percussion kit (I'm *sure* you're familiar with it) and it wouldn't trigger on the top harmonic... we had to use the next one down. That's when I found out about the fingers... you can zap 'em with a charged up capacitor if you want, we like the sound of having the top harmonic there with perc. so we didn't bother. Simply switching to platinum contacts would solve it without the switch to a low voltage design. Einstein, it's not the contacts that are cadmium... the leaves are cadmium plate. The contacts are self-cleaning, as all contacts are... but *you* knew that, right? If these are antiques, what's a retard like you doing opening them up anyway, dip****? You have all the capability of a freshly laid turd. As we can see, the anal fixation is strong in this one. __ Steve .. |

Gave us: You play pinball, and I'll play music. Appropriate, eh? I'll let you play my old Gottleib... Your name should be cower. So far the only music you have introduced into our group is flatulence. You're just ****ed because you suffer from foot in mouth disease, and need to flail your arms like a little dip****. Here... I'll clear it up for you... That **** you have from GC HAS Zinc Chloride in it. That in no way means that rosin flux has Zinc Chloride in it. Just like John said, that **** is an acid flux, NOT rosin flux, and regardless of what GC printed on the can, it is NOT meant for electronics use. So take your clueless ass back to your geetar group where you belong. You pathetic, cringing little milksop. |

But at least I'm not a MassivePrawn, rubbing my prawniness in everyone's faces... You're just ****ed because you suffer from foot in mouth disease, and need to flail your arms like a little dip****. Me: picture. You: diddley. Here... I'll clear it up for you... That **** you have from GC HAS Zinc Chloride in it. That in no way means that rosin flux has Zinc Chloride in it. It is an example of rosin flux that has been 'activated' via Zinc Chloride. Just like John said, that **** is an acid flux, NOT rosin flux, and regardless of what GC printed on the can, it is NOT meant for electronics use. No, it is not... it is activated rosin flux. So take your clueless ass back to your geetar group where you belong. You pathetic, cringing little milksop. Your flames lick me.... over and over. __ Steve .. |
