| Ground loop hum I noticed an interesting statement you made:This hum is volume-dependent and not insignificant, and is present even with nothing connected to the phono input on the back of the pre-amp. This says that your turntable is not the problem (yet!), alt... | |
| RC feedback. Back in my tube days, I often used caps with 3x or 4x the supply voltage to provide headroom for transient peaks during power on/off etc. due to the transformer's collapsing field. I'm not sure, but I also believe they have a longer life and tight... | |
| Separate ground for dedicated line Stephen (Rphsvc), I think you have all the advice you need above, but may I point you all to a recent post for some related details: impedance mismatched ? And the reference: Video & Audio: Power, Ground, EMI, Noise in Cables Glen, would you ... | |
| impedance mismatched ? Yee Ha, an opportunity to use the new reference thread: Video & Audio: Power, Ground, EMI, Noise in Cables. Can someone explain if 3 circuits are all grounded at the same point as the entire house is ground at how is a ground loop possible? M... |
