| really? .89c ground lifters? Actually, if something goes wrong with the equipment - like a B+ wire touching the chassis - you're better off sending that to ground and blowing a fuse, than letting it sit out there to electrocute your kids.04-23-10: AuxetophoneAuxetophone,If B+... | |
| really? .89c ground lifters? I wouldn't call that a ground loop. If there was something like that, it would cause the ground to be noisy. 04-23-10: AtmasphereCould it cause a ground loop hum?Why would it be any different than ground current flow from a CATV system? In both c... | |
| really? .89c ground lifters? 04-23-10: AtmasphereYes, it does not matter tube or transistor. The real issue would be if somehow there is leakage from a power transformer.04-23-10: AtmasphereAtmasphere,Speaking of transformer leakage.... Say there is a slight leakage in the p... | |
| really? .89c ground lifters? It's probably worth pointing out that the danger from lifting grounds is much higher with tube components. These typically have 300+ VDC - very deadly.04-22-10: AuxetophoneThe only way to get a shock from the B+ is to actually put yourself in seri... | |
| really? .89c ground lifters? the human body is an impedance. resistance, inductance and capacitance. You have an impedance. If there is a system fault or a lightning strike, or some such, very high voltages can pass through the equipment through you to ground.That is a lot di... | |
| really? .89c ground lifters? As an Electrical/Electronics Engineer, I am telling you that lifting the ground and you become a better ground than the house ground and electricity will take the easiest path to ground and that becomes you.Say what? Please explain how the human b... | |
| really? .89c ground lifters? Why any manufacture of audio equipment today would still be designing and building their audio equipment using the old out dated AC safety equipment type of grounding beats me.Double insulated type AC power wiring in their equipment would not cost... | |
| really? .89c ground lifters? All the PS Audio power cords have a removable ground pin for this very reason. They seem to be well thought out plugs.04-18-10: MulvelingTrue,... but you will also notice they are not approved by UL or any other recognized testing agency. On my sy... | |
| really? .89c ground lifters? Soundgasm, JMHO if you are going to lift the ground do it on all the three wire cord and plug audio equipment. Make damn sure if multiple dedicated branch circuits are used the circuits are all fed from the same Line, leg, of the electrical panel.... | |
| Amplifier Hum - A Problem Solved Is this enough DC voltage to create a hum in my amp/speakers?Danhirth04-12-10: DanhirthDanhirth,If you are hearing a hum through the speakers, jmho, the hum is not caused by DC offset voltage on the ac mains. The hum is more than likely a ground l... | |
| BSR turntable switch makes loud pop Rar1,Thanks for the conformation. Hooking the Ceramic cartridge up to a phono preamp would really amplify the signal from the cartridge I would think. Enough I would guess to pick up the arc from the power switch when switching it open. | |
| No sound from cdp. Try a different digital cable from the CDP to the DAC. If you do not have one just use an analog ic or a video coax cable. | |
| BSR turntable switch makes loud pop I had to steal the pre-amp away from my Stanton because the BSR's ceramic cartridge seems to require the special 470 ohm impedance setting.) Ceramic cartridge? If memory serves me right a ceramic cartridge does not need a phono preamp. You should ... | |

| Toasted Pre Stanwal, Ghostrider45,It seems I should not have mixed 220V with 110V in the same system.Gabriel_37 Gabriel_37 profile says he lives in the USA. I believe he has a 240V power receptacle outlet for the amp and a 120V power receptacle outlet for the... |
