| how can a line cord affect frequency response ? Spatialking, Not sure if I completely agree with the power cord acting as an RF antenna. Once energized, it has more rejection qualities, and is more susceptible to large electro-magnetic field influences. Even placing two energized cords along si... | |
| do copper, silver & gold cables sound different ? Mt10425, FYI, the term "alloy" covers the previously mentioned "non-ferrous" metals (includes magnesium and titanium), along with "ferrous" types ranging from carbon-based steel mixes, to stainless catagories. | |
| 240V to 120V Question/Advice Please The typical USA domestic home outlet current is 15 amps at 120 VAC, so utilizing a step-up transformer can provide a maximum current of 7.4-ish without tripping the breaker. What is his amp's wattage and 50/60 Hz requirements? As far as blowing a ... | |
| High priced power cable what about the romex Drubin, I appreciate and think I understand your opinion. Although, in large, power-hungry systems like mine and others, typical Romex wire gage is undersized for my amp's ideal requirements, thus the weakest link in my audio system. Me adding a 3... | |
| High priced power cable what about the romex Drubin, Excluding the power input, the entire audio system IS a series of components ("chain"). Just try upgrading everthing but your 5 watt/chnl - 10% distortion amplifier, or everything but your tiny Radio Shack speakers, or even 24 AWG speaker ... | |
| Right channel cuts out Please Help Rtilbury, Forgive the stupidity in my previous response. I read later that you DID swap your source component. Whoopsy! | |
| AC cord polarity?? Does it matter??????? Nsgarch, Thank you for the informative response, and will look into it further. I did find some interesting articles after posting my last response, but still have inquiries pertaining to non-ferrous chassis having the same effect. Lots of veteran... | |
| Right channel cuts out Please Help Rtilbury, It's not any of the caps, as a shorted one would burst, or tax the power supply section enough to blow the AC input fuse. Not the power cord because the other chnl works fine, which is connected internally to the same AC input connection... | |
| AC cord polarity?? Does it matter??????? Hsgarch, Thanks for getting back with me. Even if the neutral wasn't at zero potential, most domestic voltges provide more than adequate supply for most component DC rails and regulated circuits (+/- 0.5 to 1.0 VAC of the localized incoming supply... | |
| AC cord polarity?? Does it matter??????? Am I missing something?Typically, AC is fed into a components isolation transformer, through full rectification and large filter/storage capacitor networks accross the secondary outputs, thus producing DC voltage. This, intern, feeds all the DC ci... | |
| Need help to trouble shoot the noisy amp. Zt000, I'll e-mail you and we'll further this off line, due to trivial technical correspondance. It'll be your choice to post any resolvement/findings. In touch, | |
| Need help to trouble shoot the noisy amp. Zt000, I am a tech, but in Chicago. Before going any further, remove all interconnect and speaker cables from both amps. Plug them into the same wall outlet, one at a time, and examine/compare them again. Next, individually swap the tubes and per... | |
| Need help to trouble shoot the noisy amp. Zt000, I agree with albertporter about calling the manufacturer first, as it just takes a few minutes to verify. If not obtainable, and you have even basic electronic trouble shooting skills, and can locate a cheap volt meter (Home Depot, Radio Sh... | |
| speaker cable static sound Karmapolice, Well done! Pending any simple diagnostic advice from LAMM, at least try swapping the tubes between the amps (individually if applicable). Other than that, there are just too many internal components that could cause this intermittent ... | |
| speaker cable static sound Karmapolice, Sorry that I'm not familiar with all your audio equipment. Are both amps plugged into the same wall outlet, and/or outlet strip? If so, it's beyond my 40 years of electronics how malfunctioning strip protection circuits could single o... |
