| Can an old Thorens Table be "Over Dampend" to the point where sound is adversely effected? A lot of people like to dampen these older Thornes tables either on the interior of the wooden plinth or all over the inner metal spring board, and arm board, they use things like "Blue Tac" or that Dynamat stuff in car doors. It will kill the ... | |
| Warm-up time for amps and preamps Leaving your system on all the time can dry out the electrolytic capacitors (even on tube equipment). This statement is incorrect. Usually filter caps have the longest life if kept charged. However, they don't like heat, insofar as long life is c... | |
| Class D Technology There is about 1% of switching voltage noise on the speaker cable since filter is not perfect but, as I said before, 1/300 wavelength antenna won't radiate. In addition, electricity in speaker cable flows in both directions canceling the most ... | |
| Can an old Thorens Table be "Over Dampend" to the point where sound is adversely effected? "Atmasphere"...What is an example of damping correctly?Using an appropriate damping material (extensional when damping surfaces; constrained when damping between surfaces), not using damping when coupling is required (such as between the arm and t... | |
| Tube Physics Question Does the KT120 compress the signal, while the KT88 does not?No. | |
| Class D Technology Speaker cables would be a very poor antenna. Since wavelength of 500kHz switching frequency is 600m a typical 2m cables would be 1/300 wavelength antenna. Usually antenna becomes rapidly ineffective below 1/10 of the wavelength.That's true, b... | |
| Do equipment stands have an impact on electronics? Sure- why not? Same test, just using the Diament system. If you did this all with a sweep tone, it would be possible to show the strengths and weaknesses of the 'isolation' system under test.Sound Anchors did something very much like this- only th... | |
| Tube Tester Mutual Conductance Falling - What it Means? The tube is slightly gassy. It will work but likely will not last as long. | |
| Can an old Thorens Table be "Over Dampend" to the point where sound is adversely effected? If your damping is done correctly its impossible to overdo it. | |
| Class D Technology I'm no scientist but I understand the difference between theoretical noise and actual verifiable noise and that, empirically, only the actual noise can actually be heard. by us humans. Noise needs to be heard to exist. Class D amps are ne... | |
| Tube Power Amp Suggestions @bigdish if you really plan to keep with those speakers, the problem you are up against is that the speakers are designed for an amp than can act like a voltage source. Most of the amps suggest so far (including ours) are Power sources.The differe... | |
| Tube Physics Question As far as I can tell, the KT88 is a better tube than the KT120, which appears to be on the way out in favor of the KT150.KT120s get a lot of bad comments on account of excess distortion. Its not at all surprising that even though there is less pow... | |
| Do equipment stands have an impact on electronics? What kind of spurious signals and how was it measured? Anyone?That should not be hard to do. Place a preamp on the stand to be tested. Run the volume up with a shorted input (phono would be best). Subject the preamp in the stand to a 20Hz tone me... | |
| What are the smallest speakers that are clean and flat down to 20hz? As far as 'the room will have some influence certainly'. I completely disagree with Ralph on this because he is seriously underestimating the effect the room has on bass response and has chosen to ignore the mountain of scientific data compil... | |
| Tube Power Amp Suggestions Its impedance is rather flat at 6 ohm.They are not very easy to drive IMO. Its easy to see why when you look at the pdf. The speaker has 4 ohm impedance in the bass frequencies and rises to the 8 ohm impedance of the Festerex at 550Hz. I would cal... |
