| Capacitors across power switches? This reduces arcing damage to the switch contacts, particularly when the unit is turned off. It can also prevent pops that can be heard through the rest of the system! | |
| Is there any benefit to a tubed phono stage? transistors in general have the characteristic of loosing low level detail and adding odd-ordered harmonics that make the sound harsher.Once detail is removed and the harmonic structure is tainted, no amount of work downstream will get the music b... | |
| Seeking hot running amps Allanbhaganinfo, your analogy does not work. Class A amplifiers generate heat because they are on all the time. The engine in your car makes heat- all the time- because it is on all the time too. But it is not correct to compare the two!Class A am... | |
| Seeking hot running amps Ah yes, heat. Class A operation is the reason for heat. Fact is, if you want it to sound right, it has to be class A.I've never understood why a person would spend thousands or 10s of thousands on a stereo and then compromise the whole thing (and ... | |
| Dynaco PAS 2, want to upgrade recifier section. You can use HEXFRED diodes for the high voltage. For the filament, I recommend a 3 Amp silicon rectifier. You will have to install a small terminal strip for the rectifiers and be advised that the filter capacitors are shot! so replace them too.If... | |
| amp -preamp combination question. Loosing the resolution that a good tube preamp offers over almost any solid state is an unacceptable compromise for me. 25 years ago I ran solid state with a tube amplifier. It kinda helped with the tube amps I ran back then (to give a kind of fak... | |
| OTL or SET? Differences? FWIW, one thing that OTLs and SETs have in common is that neither has any hysteresis loss in the output transformer.SETs do not reverse the magnetic field in the transformer, and OTLs don't by definition.Removing the transformer also removes the a... | |
| Preamp Caps?Auricap,Mundorf, Hovland, jensen,solen V-Caps are actually smaller than the equivalent values in polystyrene. You might check the dimensions.If you can't afford the V-Caps, consider the Rel-Cap Teflons. | |
| Tube Question--Slight Ringing coming from one side EL34s can make a 'jingly' sound that emenates directly from the tubes- in fact from the filaments. If the output of the amplifier were shorted or open, the tubes would also make a jingly sound that would be associated with the power demands of the... | |
| Tubes in Hi-End Preamps Here's an answer for the tube question:Our ears have evolved a certain way over literally millions of years. We cannot change that. Tubes and transistors have distortions that are unique to those devices. It just so happens that tubes have distort... | |
| Preamp Caps?Auricap,Mundorf, Hovland, jensen,solen The V-Cap Teflon is one of the coupling caps in existance. There really aren't any paper and oil parts that challenge it. Paper and oil is nice, but in nearly all of them there is a slightly shelved high frequency character (mind you- not a rollof... | |
| tube preamps Never seen a transistor setup that can match the slam, bandwidth, clarity and body of a good tube setup. There's nothing wrong with setting your sights higher! | |
| Tube Question--Slight Ringing coming from one side The complaint is a description of a microphonic preamplier tube, occuring before the volume control in the signal path. The amp has nothing to do with it. | |
| Best "album" of 2006 Kate Bush's Aerial is a wonderful, broad-ranging effort by this consumate artist. The LP has a very nice full color multi-page booklet too- nice production all around. | |
| Amp for harder music with lots of sounds. There are pleny of amps that fit this bill. BTW- all amplifiers that have any guts playing classical will work fine for death metal and electronia as well. Issues of power delivery into load, bandwidth and distortion really do not care what kind o... |
