| Larry the Cable Guys @jea48 What I said before about 4 wires having the same inductance as equivalent 1 wire would be true if 4 wires fit in the diameter of solid 1 wire - not possible because od added insulation. With larger overall diameter of multiple insulated ... | |
| Larry the Cable Guys So when you parallel four 20 gauge individually insulated wires, that gives an equivalent wire gauge of 14awg wire, (15 amps), is the net inductance the same for both conductors? Each of four individual wires will have higher inductance but con... | |
| Larry the Cable Guys @jea48 I believe that he is simply wrong. Thicker wire has lower inductance. Example: 2mm dia wire (gauge 12) has inductance of 345nH/ft, while 1mm dia wire (gauge18) has inductance of 388nH/ft (not much of a difference) As for capacitance ... | |
| Larry the Cable Guys Just one observation. Thicker wire has lower inductance. The reason for splinting wire into separate strands is skin effect. For copper skin depth at 20kHz is about 0.5mm * That would suggest keeping wires thinner that gauge 18. In plain st... | |
| The Midnight Effect - Who-How? @cleeds Thank you for the info. Do I understand correctly, that some AM stations have to operate at lower power at night (and critical hours), while "some" means stations that operate at frequencies of other (older?) stations? | |
| The Midnight Effect - Who-How? Electromagnetic radiation or ambient electrical noise may play some role, but we are also getting quiet at the evening. Our internal noise is reduced and focus increased (and the booze of course). @cleeds They have to operate at reduced power,... | |
| The Midnight Effect - Who-How? @cleeds This is from FCC website: "Most AM radio stations are required by the FCC's rules to reduce their power or cease operating at night in order to avoid interference to other AM stations. FCC rules governing the daytime and nighttime oper... | |
| The Midnight Effect - Who-How? Radio stations have to reduce transmitting power at the evening per FCC regulation. It is Section 73.187 of the Federal Communications Commission's rules to reduce power from 2 hours before local sunset to 2 hours after local sunrise. | |
| Loud vs. Tactile Bass Many years ago I replaced 2.5 way with a bit larger 3 way speakers - same 30Hz extension, same amount of bass, equally tactile. The difference was in the sound of the bass - attack and decay, became more natural, more melodic. IMHO it is not bet... | |
| Wool Blankets as Room treatment Check out on second page sound absorption vs frequency. I have 2" thick 817 panels (never installed). | |
| Wool Blankets as Room treatment It will help with slap echo, but it will do nothing for mid and low frequencies. Put wool blanket over your head while playing music - what you can hear will be reflected from the wall. Even 2" thick double density (heavy), acoustic rigid fiber... | |
| Which external SSD for music streaming? To play CD music you need at least 0.18 MB/s. Any SSD will do. Buy extra one for backup. | |
| Bananas rule, spades drool. End of discussion. All Jeff Rowland amps use Cardas clamp for spades (or bare wires). It does not accept bananas. It creates extremely strong connection and rotating spade won't make it loose. I have small Rowland 102 with speaker connector and it is great (othe... | |
| Do You Buy Speakers Without Hearing Them? I bought once great speakers from few states away and then company went bankrupt. Why? Because of poor dealership base. They had only 3 places for whole US to demo them. Still love them, but there is no support in case of any problems. | |
| Easy Come Easy Go…….BOOM! Sorry for your ordeal. 63,000 amps as a peak current is not that much. I have two Siemens protectors in parallel mounted in panel - each rated 60,000 amps peak. The question is how they rated your surge, peak or average and if average then over wh... |
