| tube amplifier auto bias- accurate? Albertporter...Setting bias just at turnon would seem to be a problem for amps that are left on all the time. Also, if the amp is turned on and off, one would expect the settings to change somewhat as the amp warms up, so that a reset procedure, s... | |
| tube amplifier auto bias- accurate? Tubes108...In military equipment that I worked on we had a similar situation.... we were adjusting amplitude and phase of an AC power supply to account for variables of the load. The way to do it is to run the adjustment process until the paramete... | |
| Volume level mystery - can you solve it? Bigtee...On some balanced equipment (I have some) the use of unbalanced connection is sensed, and the gain adjusted accordingly. I have one piece that is unbalanced in, and balanced out, but unity gain through the piece is assured by this feature. | |
| Need better sound from my records, where to start? The Shure M97xE "don't get no respect" because everyone focuses on the V15xMR. The M97 is no slouch, and real real cheap. | |
| Anyone hear the Caravelle speaker and not like it? Pal...It probably means that he doesn't like ported speakers, and this is one potential problem he can cite about them. I suggest that you listen for yourself. By the way I prefer sealed speakers myself, but it's your nickle. | |
| 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... |
