| DC leakage from power amps @crazyeddy,What are you feeding the two amps with? I assume each amp has its’ own 120V 20 amp dedicated branch circuit. Roughly what is the distance, length, of the wiring from the electrical panel to the wall receptacle outlets? What are you usin... | |
| connect 2 different wire gauge to pos and neg speaker terminal Al (almarg), What is the stuff that flows through a light bulb and comes back out again through the other wire? The answer to question #1 is ELECTRIC CHARGE. Charge is a "stuff" that flows through lightbulbs, and it flows around a circuit. Normal... | |
| Need suggestions please! Electrical noise in my system and it's driving me crazy! Edit to my post above.When I spoke about cleaning the connection of the electrical service’s #6 copper ground wire at the ground rod I should have mentioned with extreme caution. There could be a lethal difference of potential, voltage, between th... | |

| Need suggestions please! Electrical noise in my system and it's driving me crazy! nutty1,212 posts 09-03-2017 1:29pmI also recently eliminated a hum by disconnecting my CATV from my system. After re-grounding it, removing the ground and trying power conditioners, I could not eliminate it until I unhooked the coax from the sys... | |
| DC leakage from power amps @crazyeddy,Not sure if it is relevant to the discussion but what are you using for speaker cables? Brand, type? Approx length? Wire gauge?. | |
| DC leakage from power amps I have a vintage Marantz 2252B I used to checked for DC offset at it speaker outputs. Note I have not powered up the receiver for about a month.The 2252B has two sets of speaker outputs, system 1 & system 2. I have a a pair of speakers connect... | |
| DC leakage from power amps I found this link doing a search. http://audiokarma.org/forums/index.php?threads/amplifier-distortion-dc-offset-and-you.5634/ As a semi-poll, I’d like to see those on this board whip out their multimeters and take a look at the DC that is being pr... | |
| connect 2 different wire gauge to pos and neg speaker terminal almarg 7,451 posts 09-02-2017 1:14pm I don’t know what the gauge of the leads is, but given that the total length of the two leads is about 8 feet I suspect the lead resistanc... | |
| connect 2 different wire gauge to pos and neg speaker terminal Correction:In my post dated 09-01-2017 8:33pm The only fuse I have on hand is a 4 amp slow blow fuse. I have an older model Fluke 87 True RMS multimeter and I checked for resistance across the fuse link end caps. With the meter set on ohms auto f... | |
| connect 2 different wire gauge to pos and neg speaker terminal @kijanki,Thank you for your informative response. From what I understand the movement of the current in the conductor is quite slow.... Correct?Electric current is a flow of electric charge and not the flow of electrons. (In fluids electric ch... |
