| How to spot a high current amps? I don't think that "high current" describes an attribute or a particular amperage threshold that is to be surpassed. Look at it this way: a 50 wpc that can double down from 8 ohms to 4 ohms will put out much less current than a 500 wpc amp that ca... | |
| Tone changes with volume True. Our ear canals, by their internal shape, are optimized for 2k to 4k frequencies - any thing above or below will very likely cause a change in tonal perception and (definitely) how we perceive relative loudness of certain frequencies. Of cour... | |
| Blue Gas in Tubes - Why? Is it Bad? It's not a problem. The blue glow is caused by trace cobalt within the tube. Cobalt is a byproduct of the tooling process of sealing the glass. | |
| capacitor explanation? Actually, "coupling" is a proper description. The capacitor couples two circuits together by the common capacitive reactance of both circuits. The capacitor provides current at the rate to keep the voltage across it constant, so a change in voltag... | |
| Converting Mark Levinson gear from 240V to 120V Send it to Madrigal, please. That is what they recommend (if it was safe or easy, the procedure would be in the owner's manual). Poking around in power supplies of hefty SS amps is deceptively dangerous.Respectfully, and with no offense to anyone,... | |
| Older home & 2 prong outlets, Help No Ground? If you have armored cable and metal outlet boxes behind the receptacles, then it's relatively easy - just replace the old receptacles with the ones of your choice. All boxes are standard, no matter how old.If you have cloth or rubber covered wires... | |
| room treatments? is it the room that's bright? Tom, I would suggest that you obtain a Radio Shack SPL meter and a Stereophile (or similar test CD) and make readings over the entire audio frequency at both the listening position and from 1-foot from each speaker. This will tell you if the probl... | |
| A new ploy for fraud? If this gentleman can write you a check drawn on a US bank, then that check is backed up by an account and routing number. Which means he can directly wire-transfer funds to his cohort in England. Or HE could cash his own check and wire away to En... | |
| Best of all worlds?????????? What's the rest of your gear? How is the listening room set up? Can't just throw up your hands and blame only the speakers. BTW, if you're looking for an "excellent overall speaker" at that price range, check out the Thiel 2.4 also. | |
| Tube myths Joint Army Navy vs Non Joint Army Navy I don't know why or where this "myth" originated, but there are instances where, at least from my experience, the military version of a tube far outclassed the civilian variant: the Sylvania 6SN7 JAN CHS VT-231 and the RCA JAN 2A3 grey plates. Fro... | |
| Help with Theta Gen Va? I had a similar situation. When I sent mine in to Theta to be upgraded to the Va, I dropped a note in with the unit and they replaced the xfmr for free. Buzz no more. | |
| How do Xover works? One capacitor, one inductor and one resistor indicates a first order crossover. The resistor is probably a 4-ohm because (maybe) one driver is probably 4-ohm and the other 8-ohm. The resistor is in series with the 4-ohm driver to give a nominal 8-... | |
| What are OA2 tubes and why are there more gear The OA2's are used in voltage regulators. One setup is to offer a 150-volt anchor to the cathode of the regulating tube. Another, it's used as a straight regulator. Usually the regulator itself is a dual-triode and each cathode of the regulator ha... | |
| How much Power do speakers really use ??????? Let's say you have two amps - one at 50 wpc and another at 5,000 wpc - with identical speakers and listening rooms. If you play both at a certain volume level, say 80 db SPL, both amps will provide the same power. However, during transient peaks, ... | |
| Were to get fuse box for dedicated line? ... I was assuming a remote panel. Installing a parallel, or subfeed panel, is a legitimate installation provided that the subfeed panel is properly bonded, grounded and supplied with neutral lugs for each circuit. In other words, it has to be a U... |
