| Quality system, make poor recordings sound better? I use bad recordings as a yeardstick to tell me how I am doing. IME, a system can 'editorialize' and can often react poorly to poor recordings, and also recordings with lots of energy.An example from the old days was Village Music of Bulgaria on N... | |
| Why do designers/manufacturers...? Tweaks huh? A long time ago we started using toroidal power transformers, and we noticed some odd things. One was that if the amps were too close together, they sounded different. Another was that the bolts supplied by the transformer manufacturer... | |
| The HH Scott 350 A MultiplexCircuitry Yes- it needs the multiplex section to be aligned. The shop will need a stereo multiplex generator to do the service. | |
| Soundlab speakers with sub woofers? Hi Bob, You got it almost completely right in your last paragraph- right up to the last sentence... so, you said The power dissipated by the speaker will fluctuate throughout the audio band inversely proportional to the impedance.Which is correct.... | |
| Most enduring audio purchase Triplanar! Its so nice to know that no matter what I throw at the system, the tone arm will track it perfectly and reliably year in and year out. | |
| Solid state "single ended" pure class A preamp Yes, I've never heard of a preamp that was not class A. | |
| Grounding Normally the ground on the AC outlet is fine.If your system needs more than that, take it as an indication that the ground circuits in one or more components in the system are not set up ideally for best results. | |
| Soundlab speakers with sub woofers? I thought I was pretty clear with my point, but maybe not. Here it is, referring to the math I posted earlier:1) many solid state amps will not get flat frequency response- if so they will be bass shy and too bright.Some people with transistor amp... | |
| Solid state "single ended" pure class A preamp SET means 'single ended triode' FWIW.If you really want some of the attributes you had before, I would steer well clear of a solid state preamp. You want a tube preamp, and probably a single ended one at that. | |
| Stand out phono stages All preamps are class A FWIW. | |
| Soundlab speakers with sub woofers? In my feeble mind I imagine a relatively fixed voltage across the speaker terminals. As the impedance changes with frequency so will the current drawn from the amp and so will the power supplied by the amp. When the impedance rises in the bass, th... | |
| Metal "whiskers" on cartridge body Zeppelin isn't metal. | |
| The HH Scott 350 A MultiplexCircuitry I would try with Antique Radio Supply in Arizona- they have a pretty wide range of can-style multi-section filter caps. I assume you are talking about rebuilding the power supply.Otherwise replacement of other caps is not going to win you much unl... | |
| Tube pin question? Stay away from any contact enhancers that are not in spray form. Quite often they have base carrier that can migrate. This can cause real trouble with tubes!DeOxit in spray form is as powerful as you would ever want! | |
| Gain of line preamplifier Yes. In such a scenario the switch is selecting a different pair of resistors for each volume control position.A shunt attenuator typically only switches one resistor. |
