| Time Needed to Break In Tubes Properly Breakin And then there are those that will never perceive any difference. Some of the changes in nuance are too subtle for many an ear. There are many systems that are simply not resolving enough, and will mask the changes. Lots of variables, but yeah- I'... | |
| Disconnect the woofer Many crossovers have a simple 1st order Butterworth section(an inductor) in series with the woofer Some let the woofer's natural inductance roll off the mids/highs. If there's more than that(a cap to ground after an inductor, balancing or EQ circu... | |
| Time Needed to Break In Tubes Properly Breakin Some info on the burn-in for 300B tubes:( http://www.stereophile.com/features/229/index6.html ) You might read the first paragraph and footnotes on page three also. I haven't found another tube that takes as long to burn-in, but most change charac... | |
| Equalizer or acoustic room treatment or? (http://www.warrengregoire.com/hifi-stereo-sony-sacd-mod.htm) Pay particular attention to the paragraph regarding the OP amps Sony uses, and the TIM they generate. Intermodulation Distortion is a major cause of listener fatigue. Further info: (htt... | |
| What tubes for ST-70 If it's using the 7199: It's probably still the stock design board, and the signal path components are on top(no need to open it up). Solens are way better than the oldies too. Happy listening! | |
| EL34s -- your picks for best? Hi again Mr B- Siemens and Tele are two different companies, but their presentation is very similar. German manufacture seems to produce a more linear/less colored sound than most others, and some systems will seem too lean/cold with them. That co... | |
| EL34s -- your picks for best? The Winged 'C'(Svetlana, St Petersberg plant) EL34s are the last I had in my modded ST-70. The performed well enough, that when I could no longer afford/find NOS Phillips ECG or GE output tubes(eight matched) for my current monoblocks, I went with... | |
| What tubes for ST-70 In this case- it's a pleasure to say, "I told you so!"(re: the Mullard in the power supply) If you're handy with a soldering iron, replace the Black Cat coupling caps with something newer(auriCap/Multicap/DynamiCap to list a few good, reasonably p... | |
| Underestimating the influence of studio monitors? To add another variable to the previous valid points, re: Recording Engineers, their abilities, knowledge and monitors: (http://www.digido.com/honor-roll.html) (http://www.digido.com/level-practices-part-2-includes-the-k-system.html) | |
| How to Attach Spade 10 AWG Solid Copper If you're referring to crimping an area of a connector that acts as a strain relief, it has no bearing on the actual connection/conductivity. Different story, and understood! | |
| How to Attach Spade 10 AWG Solid Copper That's dealing with butt connectors. I suppose you use those in your DIY audio cables too? =8^) | |
| How to Attach Spade 10 AWG Solid Copper I've been soldering and crimping cables/connections for over forty years(30 yrs in business), and would REALLY like to know what could POSSIBLY be gained by crimping ANYTHING after soldering it. GEE- a hundred, really? | |
| How to Attach Spade 10 AWG Solid Copper I one crimps at all, it should be done first, to obtain the best/most metal to metal contact. Minimum solder between the actual conductors is preferable. Once soldered, a crimp is wasted effort. Obviously- solder is a conductor also, but none will... | |
| Problem with Tube? The 7199s are a thing of the distant pass. The 6SN7W tall bottles cost over $150 each. Light bulbs are somewhat cheaper, and they don't get intermittently noisy. They simply stop working(not even close). I've replaced the noisy 6SN7Ws with new one... | |
| Problem with Tube? Sometimes tubes will develop a bad internal connection that improves as the tube heats up. I've had some that would make that noise unitl I tapped them with a pencil. They never seemed to get much worse, and since they were my hardest to find tube... |
