A little test @jbuhl Am I correct it rhymes with frugal? | |
Is it a Bad Tube or a Bad fuse (Fuse Fatigue)? That’s a pretty nice amplifier to just use a guess what caused a fuse to blow. These fuses are subminiature 250 Mv. Is that a typo mistake? Is that suppose to be 250V rated fuse? What amperage rating? How tight is the fit of the fuse in the fu... | |
Measurements for a dedicated line From dpop post: 02-23-2024 at 08:47am jea48 said: Are you sure you have an Equipment Grounding Conductor at the outlet? dpop response: 100% most definitely; on both outlets being discussed. I can take my multimeter and read 121.6 ... | |
Measurements for a dedicated line @dpop, I ran some tests for VD on a convenience receptacle outlet branch circuit. Wiring is 12/2 with ground NM cable, (Romex trade name). Length, distance, from panel to wall outlet used for test is approximately 65 ft. Nothing was plugged into... | |
Dedicated line help @tjassoc said: - There debate to use aluminum armored cables as a shielding, not sure of the results. RF shielding is not the main reason for using MC (Metal Clad) aluminum armored cable. The main reason for using 2 conductor with insulated gr... | |
Power questions I do have to tell you though that dedicated ccts do indeed often use separate neutrals Agree, a true dedicated circuit does not share a neutral with other circuits.. Therein a multiwire branch circuit. Multiwire branch circuits are not conside... | |
Power questions 2012 Seminar w-Notes v1-0.ppt - indy-aes-2012-seminar-w-notes-v1-0.pdf Check out page 16. Read pages 31 through 37. . A true dedicated branch circuit does share a neutral with other circuits. (Therein a multiwire branch circuit.) A true dedicat... | |
Can you touch the tubes? I avoid touching the print, lettering/numbers, info on old 1950s-1960s 9 pin signal tubes. The oil from fingers can smear the print on the glass. . | |
230V Preamp USA The best solution is to have electrician wire you 240 in your house and you will use best of the best. I doubt a credible licensed electrician will install a 240V branch circuit and 250V outlet to feed a 230V preamp. 2020 NEC 210.6 (A) (... | |

Riddle me this.... EDIT: Audiogon system would not let me edit just a few minutes after posting... A normal positive transient signal will cause a driver's speaker voice coil to push the cone forward. A negative signal transient will cause the voice coil to suck ... | |
Riddle me this.... The term absolute phase just confuses the discussion. Signal Absolute Polarity is the terminology that should be used, imo... A normal positive transient signal will cause a driver's speaker voice coil to push the cone forward. A negative signal ... | |
Riddle me this.... @antigrunge2 , Agree... Standouts where a definite difference could be heard? Etta James, "Love Songs". Track #1, "At Last". Change? Etta’s Voice. Polarity inverted her voice was thin. Correct polarity her voice was full, a more moving prese... | |
Riddle me this.... Correct absolute polarity at speakers. Positive signal pushing speaker cone outward. Not negative inverted polarity sucking cone inward. :) https://www.youtube.com/watch?v=axXrs55X9kE |
