| Tremendous RF problem -- phono stage is a radio As noted above, it is an absolute "must" that you use shielded cables. Also, if you have your cartridge "unloaded" (e.g., 47kohms or higher) you might try a lower figure (higher loading), such as 1,000 ohm or 150 ohm, etc. Higher loading attenuate... | |
| "Off" vs. "Standby" and tube life The safety issue is not limited to tubes. The tube itself won't start a fire, but the failure of the tube could casue other components to overheat and create a hazard. But, that is the case with solid state gear as well. Actual fires from componen... | |
| Do speakers have to "warm-up" too? I doubt that there is much warmup for speakers. Conceivably, the suspension parts (surround, the spider, etc.) could be warmed by friction, but I have never heard of that making an appreciable difference. The voice coil itself is NOT a moving part... | |
| "Off" vs. "Standby" and tube life You can put the amp into standby, or you can mute the amp, or put it into standby or you can select a different input than the CD player before turning the CD player off. The point is that the CD player MAY emit a pulse when it is turned off which... | |
| I am openning a shop. What equipment should I sell These days, I don't see anyone that is not already a well-established dealer making money on audio. It's home theater, custom installation, distributed music/video, Crestron (or the like) control system and even automobile audio that makes money. ... | |
| Tube amp warm up As the charge builds on the plates of the capacitor, they actually move a bit in relationship to one another. But, for something sitting around for a few months, that is not the issue.Still, capacitors take a very long time to come up to song, som... | |
| Tube amp warm up Probably the capacitors needed to be "reformed" by use. That is the reason people slowly bring up voltage using a variac for equipment that has been sitting for years. | |
| Tube amp warm up All of the tube amps I've owned needed about 15 minutes to sound good. Is it getting better after that period? Perhaps, but I don't kill myself trying to notice any difference -- I just know it sounds good after 10-15 minutes. Solid state stuff ta... | |
| Anybody heard the DeVore Videlity Gibbon Super 8? I only heard it in Las Vegas at, I believe, T.H.E. SHOW (show held next door to the CES tradeshow. But, even with that limited exposure, under typically less than ideal show conditions, I was quite impressed with this speaker. I personally find to... | |
| 300B tube recommendation for SET amp? Hi Onemug,Which set of trannies did Vu use in your 300b amps? I am guessing that you have his pushpull amp -- I don't recall any single ended amp that he makes with vintage transformers. I am quite familiar with his amps, both the ones with old Ch... | |
| CES Alexis Park exhibitor question I've helped a couple of exhibitors move stuff at two CES shows. The parking on the side of the Alexis Park venue is pretty close to any of the exhibition spaces. At worst, you will have to carry stuff down one corridor and down one level of stairs... | |
| Thoughts on Plasma, LCD, DLP and which way to go Fujitsu plasmas are more expensive than other brands, but I personally like the picture of their premium models. I think their processors do a very good job of avoiding motion artifacts, minimizing mosquito noise, and minimizing other picture anom... | |
| Move to NYC Apt -- Vandersteen 3A Speaker Woes Yes, the comment about the 20Hz note is nonsense. The wave may not form, but the pressure change will be sensed as though bass waves are propagating through the room. My Stax Omega II headphones have amazingly deep bass response. Given the size of... | |
| SET for Orchestral , Big Band etc. I currently run my 99 db/w efficient speakers with a SET amp using parallel 2a3s. That is plenty enough power. While I like the sound of this amp very much, I also get pretty good results with pushpull triode amps as well. I know that there are a ... | |
| Thoughts on Plasma, LCD, DLP and which way to go With modern plasma sets, I don't think you would have problems with high altitude/noise. Just one proviso, be sure to provide plenty of ventilation space around the set. The people that seem to have problems with premature death of their sets, tha... |
