| A stupid question(s) about power cords 1. It is to orient the plug correctly so the hot and neutral of the receptacle matches the hot and neutral of the equipment. 2. Not necessarily. The dummy ground pin almost never has a wire welded to it so it does not connect in any way to the... | |
| To upgrade a separate power supply? Depends on the voltage rating of the caps, what voltage is applied to the caps, and the ambient air temperature surrounding the caps. | |
| Limiting a full range driver This is one of those it-may-or-may-not things. Even if you crossover the drivers at 100hz, they are still 8-inch drivers. The midrange performance should not change since the relationship between the radiating area and wavelength (frequency) is st... | |
| is anyone using an Aurender streamer with Schiit Yggdrasil? I have it also, the Yggy DAC with the N100H. Excellent sound; you'd be hard pressed to get better at any price. However, when I first got the units about seven years ago, I had problems with uncompressed .wav and .aiff files larger than 400MB not... | |
| How does a preamp die from sitting unused for a few months? By checking the fuse did you do a visual inspection or did you do a continuity test with a multi-meter? A fuse may look fine but can be broken inside. If you don’t have a DMM replace the fuse and try again. If that doesn’t work then maybe the pow... | |
| Mysterious power tube behavior If the bias reading follows the tube then it's not the bias circuit -- the tube is bad. The fixed bias bias circuit uses a 10 ohm resistor at each cathode and the voltage is measured between cathode and ground (the voltage is converted to milliamp... | |
| 2a3 Tubes - Favorites? RCA Cunningham single plate. Nothing comes close. | |
| Measurements for a dedicated line The neutral should have no more than 2 volts to ground. If you have more than that (as measured at the receptacle) the first thing to do is to go to all the outlets with a plug in receptacle tester and make sure they all read ’wired correctly’ and... | |
| How does bi-wiring work? It doesn’t work any different than non bi-wired. From an electrical engineering standpoint, the amplifier terminal and the two speaker terminals are the exact same node. The only advantage IMO of bi-wiring is that the sonic signature of a speaker ... | |
| Modern Speaker switch for use with banana plugs Luxman AS-55. One amplifier to three pairs of speakers. You can find 'em on eBay. | |
| High output voltage DACs, preamp input concern Source output voltage is not an issue with preamps as the first thing the source voltage drives is the input impedance (usually) set by the volume pot. There are no tubes or transistors upstream of the volume pot to be overdriven. | |
| Ribbon cable inside amplifiers Those ribbon cables are most likely used for the front panel meter, That meter measures current at the output stage so it appears each wire in the ribbon picks up the voltage from a transistor (probably across the emitter resistor) to do the conve... | |
| Query on power cable with IEC C13 and US 2-prong Read your owner's manual. If the list of "what's-in-the-box" states 3-prong power cord that means the unit is made for sale in the US and Canada. If the unit is double insulated (I doubt it) then there will be no continuity between the IEC recep... | |
| REL owners, how many clicks on your gain and crossover FWIW, with my stereo pair of S/510’s the settings in my 28’x15’x8’ room are: Five clicks from 20 hz on the crossover and 12 clicks clockwise on the high level input for use with a pair of Thiel 3.6 speakers; 3 o’clock in the crossover and the sa... | |
| Blowing Fuses. Dennis Had Inspire 300B SET Turn on the amp without the tubes installed. If the fuse blows send the amp in for repair. If not, then there's a 99% chance it's a bad tube. |
