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...

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
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... 
connect 2 different wire gauge to pos and neg speaker terminal
Al,Thanks again for your response. Thanks, Jim. Regarding...Am I correct in assuming watts is a measurement of electrical energy? Watts is a unit of power, as you of course realize. Power is a quantity that is defined at a specific instant of time... 
connect 2 different wire gauge to pos and neg speaker terminal
Al, (almarg),Thank you for your responses to my questions. ... if only a voltage, (potential), is present, an electromagnet field will exist outside of the conductor/s without there being current... Correct? I’m not 100% certain, but I believe in...
