| High Level Distortion I find it hard to believe that cables, tweaks, or room treatments would produce the distortion you describe. BTW, 88 dB is not very loud in real world terms so I have to suspect some faulty electronics or a blown driver in your speakers. Play at a... | |
| Anyone Blow a Release Valve on Power Caps? Actually, to get 600 watts into 8 ohms requires 100 volts across the caps, so they must be using a pair in series for each voltage rail. The voltage is additive but the capacitance is halved so you have the equivalent of a pair of 126 volt 41,000 ... | |
| Microzotl start-up filament flare? The reason is that the resistance of the filament increases dramatically when it gets hot. So when you first turn on the amp, the filaments are cold and there is less resistance to current, so a larger amount of current flows through them until th... | |
| Anyone Blow a Release Valve on Power Caps? A side note to Sean's post, the large "beer can" electrolytics such as you have in your amp all have a small valve (looks like a small rubber bump on the side where the wires connect) that will release the gases that form if the cap breaks down. W... | |
| Anyone Blow a Release Valve on Power Caps? Electrolytic caps blow because:a: they had too much voltage across them, i.e bad designb: they broke down due to some internal defect, i.e. bad capThe volume you play the amp at has nothing to do with it. Assuming a good design that doesn't put to... | |
| How do you measure output impedance? Sorry, but you really can't simplify it any more than I described. Maybe it could be described better, but that is the process. It really isn't all that complicated. You can get the parts at Radio Shack for a few $$.The modifications done to your ... | |
| Transport rumble? This is a well documented problem with some Toshiba players. I believe the Toshiba solution is to replace the transport. An authorized Toshiba repair center should be able to answer your question. | |
| How do you measure output impedance? It is very simple if you can hook up a potentiometer to the output of the preamp. Use a value that has a maximum value at least 10 times the estimated output impedance, 25K ohms should be enough.Feed the preamp a fixed level signal such as a refer... | |
| Do I need a machine to clean ? Besides the convenience of being less labor intensive, the more expensive machines do a better job because they have more powerful suction. I had the entry level AA machine and it never got all of the fluid off the record no matter how long I spun... | |
| Stands make a huge difference with ProAc Warren, I cringe when I read posts from people who claim that they have found the holy grail and that the way they are doing it is the only way. While your stands are designed around a valid concept, just because it works with your speakers on you... | |
| Dealing with an unstable, vibrating wood floor... If your walls aren't strong enough to hold a spice rack then you need to move. | |
| Impressions on Talking Heads Box Set What box set are you referring to? | |
| Is solid state on the brink of extinction? It is impossible to comment since you only listed one piece (Acoustic Reality eAR 2 MKII Class D amp) in your post. Not knowing what you had, and what you now have, makes it impossible to assess whether you upgraded or not. Less expensive, current... | |
| UPS is in bed with the devil, It wouldn't be so bad if they had charged me an overweight fee AND delivered them, but to charge extra and then return them is not right. I did look through their 24 page legal disclaimer and the fee is in there and it says it is their option to d... | |
| What Pre in connection with a C-J Pr 11A? Your question is impossible to answer without knowing what you are willing/able to spend. Preamps run from a few hundred to many thousands of dollars. While higher price does not always mean better performance, there is some correlation. |
