| Bad NOS tubes... aolmrd1241 said:Pins were clean.Did you clean them?When were the tubes manufactured? Gold plated steel pins I assume?How tight do the pins of the tubes fit the tube socket female contacts?Did your tubes come boxed like this?Copy and paste between ... | |
| Bad NOS tubes... aolmrd1241 said:"After 2-3 months of use I started to hear unacceptable levels of noise from my speakers,you know, the dirty sound of that dreaded tube noise of a scratching, distorted, dirty volume pot type of noise,which totally infringes upon t... | |
| Direction of aftermarket fuses (only for believers!) atmashere said:^^ You won’t have arcing- that would be audible! A small amount of arcing has a way of turning into a lot of it in a short period of time...Well that depends. On the AC mains side it depends on the size of the conductors and or the ... | |
| Direction of aftermarket fuses (only for believers!) I’m reminded of a post by herman.Quote:"If you say the AC fuse blew because there was too much current flowing through it everybody nods in agreement even though that isn’t true. If you say the wire in the fuse melted because it got too hot after ... | |
| Direction of aftermarket fuses (only for believers!) I would add IF the contact between the fuse end caps and fuse holder clip/s contact/s are such that a VD can be measured (From fuse clip to fuse clip) then what else can/is going on in the poor connection? Maybe an ever so slight arcing between th... | |
| Direction of aftermarket fuses (only for believers!) Al,Thanks for the clarification. Jim | |
| Direction of aftermarket fuses (only for believers!) atmashere said: In one of our preamps I measured a 158mV (0.158V) drop; in one of our amps I’ve seen a 2 volt drop cause a loss of 40 watts at the output of the amp. A fuse is one of those spots in that set of connections from the wall (AC power c... | |
| Direction of aftermarket fuses (only for believers!) Hi Al,Just read your post. I should have done a better job of what I was trying to say. After reading your post, I can see why Ralph took it the wrong way. | |
| Direction of aftermarket fuses (only for believers!) atmaspere said:Its more than just millivolts- I can measure the effects with a 3 1/2 digit voltmeter. Mitch2’s suggestion by the way is excellent and is also measurable. Some fuseholders (like panel mount units) won’t allow this.In response to my ... | |

| Direction of aftermarket fuses (only for believers!) atmasphere, Again, great post. The best explanation I have heard to date for fuse directionality. I would think it should satisfy those that have experimented with fuse directionality and say they can hear a difference. I would think it should ... | |

| Direction of aftermarket fuses (only for believers!) geoffkait,What part don't you understand? You're continually trying to nitpick responses with certain people in threads. Sometimes asking for proof and then you will say in the same thread to take your word as the gospel. I think you just love to ... | |

IMO the methodolo... |
