| Just got Audible Illusions L1, but it sound harsh Quote from Joe's Tube Lore."Special warning to Audible Illusions preamp users:The one thing you can say for the Sovtek is that you can run it hard and it can take it - and apparently thatÂ’s exactly what AI does. Unfortunately the classic NOS tubes... | |

| Electrician's advice wanted: safely lifting ground Yes, it is two paths to ground when one amp has a connection from input to chassis ground and one does not. Because chassis ground is relative to the transformer ground on each amp, and the transformers don't tap at the exact same voltage, so ther... | |
| really? .89c ground lifters? Also, some equipment with three prong power cable actually have the ground lifted inside the chassis. I've owned several amps wired this way.04-25-10: AlbertporterIf the amps are UL and or CSA listed then that would imply the AC power wiring of th... | |
| really? .89c ground lifters? ...how can I tell whether my equipment is a three wire cord and plug deal or the kind that's safe?04-24-10: AuxetophoneAuxetophone,In the case of a three wire cord and plug if the equipment ground is not lifted and the electrical continuity integr... | |

| Do better ingredients make a better Ground Wire? People..... my understanding of this thing is that the other end of the wire is not connected to earth ground.(AKA, the safety equipment grounding conductor.) It is not connected to anything.Example of, I believe.http://www.audioasylum.com/audio/c... | |
| 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... |
