mike stehr Posted February 4, 2002 Share Posted February 4, 2002 You are doing a Noble thing, Horn ED. Whether it's your Mother or not. I'm just Envious because I have two SVS 16/46's and no amp to use them with! I have a amp, but it's underpowered and tired. I tried the Subs with the Amp, I think they are deep and very musical. I geuss I got a little discouraged when Tom and Ken chime in with the JBL tent $220 dual 18' sub sale, And I just dumped $1100 on a pair of 16/46's and still need a amp. But that's okay, I wouldn't had the room for a JBL cab. That's the nice thing about the SVS's, little footprint. It won't be long, I'll have a sub amp. (And I'm enjoying 2 channel at the moment, anyway.) Wah. Quote Link to comment Share on other sites More sharing options...
HornEd Posted February 4, 2002 Share Posted February 4, 2002 Mike, save your crocodile tears... you should be able to pick up a used stereo power amp and wire it for 4 ohms... and that will bring those tubes to life. All you need is clean quiet power... feeding each about 350 watts at 4 ohms and your name will be upon all your neighbors lips... HornEd PS: You can always pick up a better, more expensive choice down the road. Quote Link to comment Share on other sites More sharing options...
mike stehr Posted February 4, 2002 Share Posted February 4, 2002 Right now HornED, I can't even pay attention. Not long, though. Quote Link to comment Share on other sites More sharing options...
kenratboy Posted February 4, 2002 Share Posted February 4, 2002 As of now, to power my JBL sub, I have a 180 watt plate amp I purchased for $150, I see no reason to replace it, it drives those woofers HARD. Anyway, its amazing how weak some amps are. I tried two amps before I got the plate amp. The first was an Aiwa bookshelf receiver, well, NO! Even at full volume, the woofers wouldnt even move to a visible extent. The second was a Mitsubishi stereo receiver that came with a big-screen in 1991, it wasnt ANY better, I thought it was a $200 receiver, but it was crap, too. Anyway, when I got the plate amp, I was nervous to see if it would even DRIVE the woofer (only one now, arrived at JBL in Northridge today for fixn) well, to say it drove the woofer would be a gross understatement. To be honest, I have NEVER sat down with a high-end stereo system and listened to it, Good Guys demo room on a weekend is the best I have done, I think I should remedy that. Once, I went to an audio shop in L.A., and I was lucky enough for the owner to show me a surround system make of B&W 801s, Krell-everything, and a 9 Vidikron CRT projector. It was about a quarter-million dollars. It would have probably cost $100 in electricity and wear to fire it up, but I was in a trance for the rest of the day, I went to listen to some B&W 600 series bookshelf speakers (SORRY, before I discovered Klipsch.) Question to everyone else, what is the most expensive stereo/home theater system you have ever listened to? My dream is to see some Wilson Audio league speakers, even if they are overrated crap.

HornEd Posted February 4, 2002 Share Posted February 4, 2002 Kenratboy, thanks for sharing your experience on what works and what doesn't for pumping up the bass. How about a few more from others who have made big woofers sit up and take notice? By the way, I may be in Reno later this Spring. I have an urge to build another small business and Nevada has the best small corporation friendly laws in the nation. I am being encouraged to return to the publishing business and publish short run (2,500 min) perfect bound paperback books on specialty fields. If I do, I shall distribute them form Reno or Las Vegas and save buyers everywhere sales taxes. How do you like Reno? HornEd Quote Link to comment Share on other sites More sharing options...
mike stehr Posted February 5, 2002 Share Posted February 5, 2002 Well hopefully if I can get this amp to idle like it should or at a reasonable temp, and get the DC offset down to 0 volts, I can be doing the bass thing for a little bit anyway. I replaced the Trim pots for Biasing the output Transistors, these are better pots with more adjustment, the guy at the local electronics place always feels sorry for me because they never have anything I want, so he just gave me the pots and some .1uF film and foil caps too. I just put it back together and plugged it in, it didn't explode, so now I can break out the multimeter and hopefully set the bias on this damn thing. You gave some insight on giving this amp another shot,HornED. But I'm not gonna bet on it, the ol' NAD transistors are pretty tired. OKAY>>> I managed to get the thing biased. It should be 15mA, but I could only get it to even out at about 40mA. I couldn't get both sides to stay at 15mA, they would drift beyond the 2.5mA tolerance. It runs warmer but I think it will be okay. I'll try Tomorrow and see if it will take another shot at the SVS's,(Hope! Hope!). These pots really helped on keeping these transistors from drifting all over. Isn't this about the most boring post you ever read? THANX!

kenratboy Posted February 5, 2002 Share Posted February 5, 2002 HornEd: Reno is the nicest place I have ever lived. I am NOT lying to you when I say that I have lived in the following places: Bay Area (Concord & Martinez), L.A. (Toluca Lake), San Diego, London, England, and Hobart, Tasmania; All for work. Although all of these places were fun to visit, they sucked as far as day-to-day living is concerned. In Reno, nothing is overpriced, crime is low, schools are fantastic, availability to shops is great (no high-end audio selection, but thats not as important as day-to-day living), and there are no big negative points. Most people that visit Reno see the airport, the shuttle bus, and the downtown casinos. THAT IS NOT RENO. The area surrounding downtown is not great (like lots of L.A. city) but as soon as you get about two or three miles from downtown, you start to see the real Reno (clue if you visit.) I live in South Reno (if you get a map, near Mt. Rose Highway, in Galena) and although the average home price is over $300,000, cheap stuff can be found in the North or closer to town. There is much to say, but I have lived here for two years and have loved every day here. I have lived in the Bay Area for many years, and visited recently (relatives), and I can say the Bay Area is an armpit compared to most of the Bay Area, I dont necessarily mean that in a bad way, lots of good memories. As far as gambling goes, there are mini-casinos at big stores and gas stations, but if you dont like to gamble, they do not interfere with your life at all. The best thing about Reno, is its growing very fast, when I got here, there was a housing development called Double Diamond, it was tiny when I got here in January 2000, but now it is a monster and its just a lot of fun with all of the change. Another thing: NO TRAFFIC, ONLY 20 MINUITS TO TRAVEL CLEAR ACROSS THE VALLEY, TRY THAT IN THE BAY AREA! Also, if you like skiing or Lake Tahoe, they are less than an hour away. I will answer any specific questions if you want. Quote Link to comment Share on other sites More sharing options...
