Feb 01, 2003	Question about Sufficient Gain for LO MC Yes, you just add up all the gains from the phono stage, line stage, and step up device( if there is one), and you have the total gain.The reason why the amp sensitivity is important, is that the output of the preamp will be a certain voltage, dep...
Jan 31, 2003	Question about Sufficient Gain for LO MC I used a 0.27mv output cartridge before the one I have now, and it was just perfect with 66db gain in the phono section and 20db in the linestage. But I have a very low input sensitivity on my amp of only 0.3v for max output.If your amp is fairly ...
Jan 31, 2003	OTL Tube Amps-- are they superior to everything? Sorry I came down so hard on you Saxo.
Jan 31, 2003	6 Components + A Big Amp: Which rack? No turntable should be on the same rack with the equipment. The turntable should have a dedicated stand with nothing else on it. Suspension TTs use lightweight rigid stands. Mass-coupled suspensionless use heavy rigid stands.
Jan 31, 2003	Setting VTA on a new Shelter 901? 100 ohms is where it should be. Also a hair down in the back, just like 4yanx says. The cartridge is broken in after 40 hours. There is no need to wait beyond that for making your final adjustments.
Jan 31, 2003	OTL Tube Amps-- are they superior to everything? The Berning amp uses a high-speed switching supply instead of a normal power transformer. This was discovered to be superior about 20 years ago. So much for that argument.You don't have to like the amp. But judge it on its merits, and not its weig...
Jan 30, 2003	OTL Tube Amps-- are they superior to everything? Saxo, you have alot to learn. Is the poundage of heat sinks or the glitziness of a face plate the measure of an amplifier, in your opinion?Do you buy your amps by the pound?FYI, Berning has about the best reliability reputation over the last 25 ye...

Jan 30, 2003	To "Step up", or not? Mike, it's hard to say with certainty what output level from the cartridge will be enough. There are other factors, such as the amp input sensitivity level, that could play into this equation.The problem with trying a cartidge that is on the low e...
Jan 30, 2003	To "Step up", or not? Rmueller01, I predict that with the gain you have in the phono stage and line stage, that the output will be sufficient for the Shelter 501.Load the cartridge at 100 ohms.
Jan 30, 2003	OTL Tube Amps-- are they superior to everything? Yes, Allan, I studied this quite a bit before getting into Berning's amps. I also know about the RF carrier, and the "bus stop" get-on, and get-off routine. But I felt it was of no use to get into that here, because nobody has understood it previo...
Jan 30, 2003	Seeking Great Cool Runnin' SS Amp... How about a cool running tube amp like the David Berning ZH270? You might even like it enough to use it in the winter too.
Jan 30, 2003	Can you ever have too much power? Yes, I used to think that I needed a 3.5 watt 2A3 amp, but I found out that my system did all I wanted with a 2 watt 45 amp instead.
Jan 30, 2003	OTL Tube Amps-- are they superior to everything? Tubegroover, according to David's discussions, the ZOTL circuit is a transformer emulator circuit. It provides the impedance matching without the turns-ratio limitations and saturation limitations of traditional output transfomers. The circuit emu...
Jan 30, 2003	To "Step up", or not? As Ultrakaz stated above, it depends upon just what level of performance you are after, and how much you are willing to spend to get it. The lower ouput cartridges generally are better, and also require more gain. You can do it with a higher gain ...
