| What is clipping? Clipping is the term for the graphical indication (on an oscilloscope) of the waveform of the signal (music) being deformed because the amplifier has reached and exceeded its maximum power. Said a simpler way, it's the product of any ampifier stag... | |
| What is "slope"??? So you're talking about the high-pass filter to the Thiels?If so, my 1st response is 'why bother'? Using any of these filters introduces phase errors into the bass and midrange frequencies. Also, it sounds as if you're using one subwoof, so filter... | |
| Surround Speaker cabling question "For left and right front channels, using excellent quality cabling, would you hear a difference between 1.5m for one side and 5m for the other?"My opinion is 'no'. I'm running 4- and 9-foot lengths of premium cables to my L/R speakers. The one cl... | |
| What is "slope"??? M, is this a high- or low-pass filter? Do you have large, full-range speakers or ones with relatively limited bass output? Do the main speakers have plenty of power-handling capability full range or can you overdrive them at YOUR normal, high list... | |
| What is "slope"??? "Expanding just a bit on Marakanetz's response, the slope is the decrease in signal strength per octave. So a first order cross-over has a slope of -3db and it goes up from there -- second is -6, third is -12, fourth is -24. The decrease begins at... | |
| Good 6550/KT88 tubes See http://store.yahoo.com/thetubestore/kt8890100types.html and http://store.tubedepot.com/6550kt88.html for info and prices.I'm in the same boat as you, with a new-to-me c-j Premier Eleven-A. | |
| Tube Amp Suggestions Sensitivity and impedance of your speakers? | |
| Question on imput impedance and gain when bi-ampin You don't need to even know the input impedance of the poweramps unless you're filtering them passively or using a tubed preamp with high output impedance which may not be able to drive both amps well. You'll probably need gain controls on at leas... | |
| Insides of Lazarus H-1A amp... Jsujo, there are lots of improvements a knowledgeable technician can make to an H-1. It's full of capacitors and resistors, large and small, that can be upgraded. I've started upgrading caps on mine, replacing the lo-voltage PS bypasses on the bot... | |
| Which Beethoven's symphony do you like the best? My my...For me, the 9th is tied with numbers 1 and 2 as my least favorites. I'm an unabashed Romantic. I love #3, 5, 6, and 7. Numbers 4 and 8 are a little lite-weight for me.I like them all played strongly and not fast...no Toscanini for me! | |
| Insides of Lazarus H-1A amp... "I wonder if a good tech can take the H-1 to H-1A level? risky without schematics?"Uuh...what would the tech DO? Without a H-1A schematic diagram and an H-1 amp, he/she wouldn't know what the differences (= upgrades) are. | |
| Insides of Lazarus H-1A amp... Adonati, thx much. I've e-mailed them.Fiddler, Lazarus's owner/designer is named Greg something. As a dealer in the '80s I did business with him.Muse, huh? | |
| advantage or disadvantage going biwire vs single From my limited knowledge and perceptions, here are some advantages of biwiring.1. The larger magnetic fields created by the bass signals don't modulate that of the high-frequency circuit.2. Especially with a 3-way system (or at least one with a l... | |
| Insides of Lazarus H-1A amp... Well, 'pure' class A or 'TRUE' class A, my H1 sounds quite good. I just wish I could find a schematic diagram for it. Any of you owners have one or know where I can get one? I'm willing to pay something. | |
| Upgrading Power Supply Caps M, I'm sure some will say that these are the most-important caps in the amp. I don't agree totally with that, but conrad-johnson seems to believe it--some of their preamps use only film caps instead of electrolytics (els) in the PS. I can remember... |
