| Volume level mystery - can you solve it? Kdl6769..The little button is your problem for sure. When an amp with balanced inputs is operated single ended the (-) pin of the input connector must be grounded. That's what the switch does. Gunbei...When the two amps are both driven by the prea... | |
| Volume level mystery - can you solve it? Gain of the more powerful amp (volts out per volt in) can be lower than the less powerful amp. It's just that the more powerful amp will continue increasing it's output beyond the voltage where the less powerful amp quits. Like the story of the ra... | |
| Inverting and or non inverting amp? Elgordo...Sorry if I misunderstood you. I thought you were just pointing out that absolute phase is not maintained in recordings. I'm told that different recordings are different, different cuts on a given recording, and even different tracks in a... | |
| Anyone hear the Caravelle speaker and not like it? Theaudiotweak...Unless the amp is bridged, or is one of the new digital amps, the output is unbalanced anyway, and I don't see how location of the crossover would affect it.If you really think this is important it would be easy enough to split the... | |
| H2O Owner Survey ? Muralman1...God forbid, but Henry could get run over by a truck. As I said, the schematic, and better still, a service manual, would eliminate the concern expressed by Loontoon. | |
| Coolest looking vintage tuner..... H.H. Scott equipment was always thought of as beautiful. I have an old tuner that I built as a kit stowed away in a closet because it is too nice to get rid of. "Good stuff", all of it! | |
| H2O Owner Survey ? Does Mr Ho provide a schematic and parts list when you buy his amp? This used to be common practice for audio electronics (and is still the norm for pro equipment). With this information any competent electronic shop should be able to fix the amp.... | |
| Anyone hear the Caravelle speaker and not like it? Theaudiotweak...I didn't mention it before, but why should the amplifier care where the crossover network is located? Try hooking up the speaker with red and black wires reversed, so that the crossover is in the return leg. Does it sound any diffe... | |
| Speaker cable vs. interconnect cable length If it were me I would go with the 20 foot interconnects. | |
| Anyone hear the Caravelle speaker and not like it? Theaudiotweak...In the basic parallel crossover no signal is "dumped to ground". In some cases a crossover may include a RLC network that damps woofer driver resonance, and this will shunt a very small proportion of power at a particular frequency... | |
| Speaker cable vs. interconnect cable length Tonyptony...You will get all kinds of opinions on this. Mine is that if your preamp has output impedance of about 100 ohms or less (ss usually runs around 50 ohms) long interconnects should be no problem. For tube circuitry, where 600 ohms is not ... | |
| Speaker cable vs. interconnect cable length Tonyptony...If you use rca inputs/outputs (with an adapter)the interconnect will be an unbalanced interface even if the wires and XLR connectors are configured for balanced use. When balanced interconnects are used in unbalanced mode signal pin(-)... | |
| Anyone hear the Caravelle speaker and not like it? Comparison with other box speakers is reasonable, althoughthe stunt suggested by Onhwy61 is over the top. On the other hand, no box speaker should be compared with planar or open baffle speakers because the spatial distribution characteristics are... | |
| tube amplifier auto bias- accurate? Bin...Actually it was Ed_sawyer who suggested that a voltage measurement was all that is required, and I merely pointed out that you can utilize a scope as a voltmeter. It doesn't make sense to do that, (like adding on the log scale of your slider... | |
| Microphonic Amps? Gaffer74...Think about it...a phono pickup is designed expressly to pick up small vibrations, whereas tubes are designed to minimize microphonics. Turntable vibration control is essential although IMHO it calls for common sense more than expensive... |
