What does Nominal Impedance mean? Incidentally I have never seen a speaker whose impedence measures a flat 2.5-3 ohms over 100-10k Hz. Have you? I have the Thiel 3.6's. From Stereophile: | |
What does Nominal Impedance mean? Nominal means "in name only" and has little to do with the actual impedance of the speaker. That’s why it’s confusing. The speaker impedance is measured across the frequency band and someone at the speaker company looks at it and says hmmm... that... | |
The "audiophile gear" I REALLY need is a damn house. Headphones. Good ones, along with a top notch amp and dac. You'll never go back to a mid level two channel system again. | |
Anyone know what would cause an amp to cut out briefly? Or it's a manufacturing defect. It's a symptom of a joint that wasn't soldered. First place to check is where the B+ splits to the power tube plates. | |

Willsenton R300 Circuit Design Issue Now I see what’s going on. First, the 6SL7 will be damaged with 400v because its max plate voltage is 300 volts. This is a simple common cathode amplifier. The 200K plate resistor and 400V B+ at 120 volts yields a plate current of about 1mA per s... | |
Willsenton R300 Circuit Design Issue May I respectfully suggest that you do not turn on that amplifier until you are sure of what you did. The 1N5380B is not a diode, it’s a zener diode and its breakdown voltage is 120V. That means it either maintains 120 volts (regulator) or it dro... | |

Help-Looking for Service Manual for ML 23.5 The reason you probably can’t remove the copper bar is because it has two downward bends and connects the two smaller 1900uF regulator caps. Those caps are tough to get to and you’ll need a 5/16 hex box wrench to get the wires off (screwdriver won... | |
Huge difference in sustain in a single string? Could me a manufacturing defect, try another one. If the issue remains, check the saddle to see if it moved from where it should be for proper intonation. Also check the nut to see if any gunk is at the bottom of the groove. | |
20amp v 15amp If the wall outlet is 15-amp 125V then you'll need either a 20 amp to 15 amp plug adapter or a one foot 20/15 power cord. Each are less than 10 dollars. But if you know how to replace a receptacle, then install a combo 15/20 amp 250V receptacle. ... | |
Power cord - 5 ft vs 10 ft ? Theoretically, since all power cords have a resistance per foot, the ideal length would be as short as practical. If by 'performance' you mean as low of a voltage drop to the amp as possible. | |
Need advice with clicking noise from my tube amp To narrow it down, I would try running an extension cord to another outlet (not on the audio circuit) and see if the problem repeats. | |
AR Classic 60 Bias Confusion The tech most likely got it right with a bias of 32.5ma. Based on the manual, there is a plate voltage of 420V and a bias of -46 V. If the output transformer is between 4 and 6k ohms, then 65 ma is the correct bias for the 6550 tube as it operate... | |
Dedicated power circuits Cutler Hammer is now Eaton, whose products are available everywhere. Use hospital grade outlets for your audio. These outlets have a tighter grip on the prongs of the power cord which is much more effective preventing noise from entering than what... |
