In Reply to: apologies for not being clear. I meant B+ ground. (nt) posted by jarthel on April 20, 2007 at 22:45:34:
So your answer is in my 1st reply = do not twist power supply negative around B+ wire or AC Mains wires. AC must flow in BOTH wires for a twisted pair to achieve a null effect (as with heater supply). And BTW, your initial included web addy does not work. Per clarity & confusion avoidance: Realize the only operational requirement for an audio circut to have an Earth Ground connection is the SAFETY connection. Otherwise, there is NO actual Ground in the circut; such nomenclature is an archaic carry-over from the 1st early days of crystal Radio in whicn an actual Antenna circut connection to Earth was neccessary to boost weak signal strength of passive components. The Old Timers erroneously & unneccesarily continued to refer to such current returns as *ground* when active devices (tubes) became available, because such was their habit. Today, circut Common is a more relative term towards understanding actual circut operation. Hope this helps & have a bad weekend (where *bad* in this instance actually means a good time!).
