| Question on NOS tubes bias doubt "Transconductance" IS how you measure the "gain" of an electronic device(tube, op-amp or transistor). You'll note that it is determined by finding the difference between the voltage at the input and the current at the output of the device in quest... | |
| Threshold and Magnepan Mr J- Personally, I used a Dahlquist DQ-LP1(slightly modded) for bi-amping planars(Acoustats and Maggies) in my systems for about 25 years. They are still available on the used market and very popular. See page 13 of this newsletter for a little i... | |
| Threshold and Magnepan Mr J- Keep in mind that the MMG rolls off quickly below 80hz. If you have a hunger for the bottom octaves while listening to "all types of music": You may have to consider a subwoofer. The MG12 or 1.6's wouldn't suffer that lack. All are excellent... | |
| Question on NOS tubes bias doubt The Ken-Rads are some of the best VT-231's out there, but like anything else: They're not always perfect. You bought a pair of unmatched tubes. A slight mismatch shouldn't be noticable. That you have to compensate with a balance control says they'... | |
| why are two subs harder to place than full range? Good subwoofers belong in the corners of your room so they can properly load it. Your mains belong out further into the room to avoid boundary effects(study 'The Allison Effect'). The problem then is the time alignment between the subs and the mai... | |
| Top resistors Mr M- A wealth of info! | |
| Damsel in Distress with Jadis DPL Mr M- I stand corrected! I've only seen this thread. Happy listening! | |
| Looking for good quality vintage speakers Johnny- You mentioned the "headaches" associated with some older speakers, related to their foam surrounds and I concur completely. Then you suggest speakers with Heil Air motion Tweeters and all the headaches that they provided when the accordian... | |
| Top resistors Carbon composition resistors are some of the worst as far as noise. Here's a decent treatise on the subject: (http://www.aikenamps.com/ResistorNoise.htm) Note what he says about wire-wounds and inductance. As you mentioned Mr D: The carbon comps D... | |
| Dahlquist DQ12 replacement woofers? I don't blame you a bit. Dahlquist made some great(some revolutionary) stuff over the years. I had a DQ-LP1(modded) in my system for 26 years, 'cause I couldn't find a better Hi/Lo pass filter with which to bi-amp. Then I sold it for more than wha... | |
| Dahlquist DQ12 replacement woofers? If you keep your ear to the ground(when you're not listening to your music), you might find someone selling a pair of DQ-12s on eBay or in here, that hasn't discarded the woofers, or perhaps, still has the originals in the system. Don't ya hate ha... | |
| Audio Magic and other Power Line Conditioners Thanks for that info on the PulseGen guys! (Intriguing!) | |
| Top resistors I've been using Vishay Bulk Foils for a number of years, and have had excellent results. Supposedly wire-wounds are actually quieter, but there are other factors involved in the transparency of a resistor as well. Michael percy will match parts wi... | |
| Looking for good quality vintage speakers If I'm not mistaken(wouldn't be the first time if I was): Weren't those Cambridge systems designed by Henry Kloss? You could do a whole lot worse than a free system from one of the better, old-time designers. They won't compare with an original co... | |
| Damsel in Distress with Jadis DPL Mr M- If you'd bother to read the posts: I was trying to teach Vett(or anyone else that might be interested in NOS tubes) a little something about 6SN7s(a subject HE brought up). Or- isn't that allowed on your site? OH! What exactly do "knobs" hav... |
