| Thought on OTL tube amps Hi Psag,I had looked at the writeup at his site, and also at the patent which it references. There is a transformer between the outputs of the power tubes and the output of the amplifier, along with some solid state switching devices. As I read th... | |
| Peachtree Audio Nova - No subwoofer connection ZD, with nearly all systems you would be correct, but not in this case. Jim (Broadstone), I'll start with what is most important:DO NOT CONNECT THE SUB TO THE OUTPUTS OF THE PEACHTREE 220 AMPLIFIER, unless Peachtree says it's ok, and they have sai... | |
| Elrog 300B vs Takatsuki 300B tubes 10-27-15: Dracule1Thanks Al. I got the distinct impression from George at TubesUSA to stay away from rectifier tubes that draws more than 2 amps. The list of rectifiers recommended by George for the Elrog 300Bs I think draw no more than around 2 ... | |
| Elrog 300B vs Takatsuki 300B tubes As a point of information, the Big 7 is indicated at the Lampi site as being supplied with one of the following rectifiers. I've determined the filament currents listed for each tube from datasheets that can be found elsewhere on the web:5C3S (fil... | |
| Thought on OTL tube amps 10-27-15: MapmanChalice Audio Grail amps are interesting to me. I didn't realize a SET amp could produce 50 w/ch into 8 ohm. How do they do that?Mapman, it uses a parallel pair of type 845 tubes, which I believe were originally developed for trans... | |
| Elrog 300B vs Takatsuki 300B tubes 10-27-15: Dracule1Thanks Al, for the detailed explanation. Can you point out where on the lampizator site it states the rectifier filament current needs to between 2.4 to 3.0 amps? I'm currently using the Psvane 274B replica tube. Does this tube h... | |
| Elrog 300B vs Takatsuki 300B tubes While I'm hesitant to question George's recommendations, FWIW I don't understand some of them. According to my documentation and my understanding, the 5AR4 (which he advises against) is two-way interchangeable with, and therefore very similar to, ... | |
| Elrog 300B vs Takatsuki 300B tubes 10-25-15: Charles1dadHi Al,Good point, but interestingly Wyan001 and Germanboxers use the same DAC with superb results.Thanks for pointing that out, Charles. In looking at the Lampi site, though, I see that Dracule's GG is described as having a ch... | |
| Elrog 300B vs Takatsuki 300B tubes If it can somehow be ascertained, it would be interesting to know what grid and plate voltages the Lampi operates the 300B at. I wouldn't be surprised if those voltages were considerably lower than in the Franks or other 300B power amps, and if th... | |
| Absolute top tier DAC for standard res Redbook CD 10-25-15: DgarretsonGeorgelofi, do you recall if the Theta Gen Va is an R2R? I can't find a spec, but there are some on the forums who believe so. I have one in storage that I haven't listened to in years. If it's an R2R then I'll dust it off for ... | |
| Parasound P5 McIntosh MC402 mismatch? It appears that if the 8 ohm tap of the MC402 is used the two amps have essentially the same voltage gain. So if you are using the 8 ohm tap I don't know what might account for the lessened volume. However if you are using the 4 ohm tap or the 2 o... | |
| Parasound A21 or Odyssey Stratus What preamp will you be using with the amp? The reason I ask is that both amps have input impedances that are a bit on the low side, especially the Stratos at 22K. That is low enough to be a less than optimal match for some preamps, especially som... | |
| The new Tube Technology Isn't Korg more of a pro/musical instruments divisioncompany?Yes, it is. I'd have some skepticism regarding the potential for this technology to be well received in high end audio. Which is reinforced in my mind by the reference to vacuum fluoresc... | |
| RCA Shorting Plugs vs Caps non-shorting ? Seconding the comments by Rello and Bdp24, if you were to put a shorting plug on an unused analog output, you would be stressing the circuit which drives that output, by causing it to supply a greater than normal amount of current. Whether or not ... | |
| Is it possible to adapt kt88 to a 6A3 single ended Great post, Larry, as always! And I think that your "can guppies live in milk" analogy captures the essence of this discussion perfectly.Mapman, thanks also. And thanks to Bill (Brownsfan) as well, for the best chuckle of the day :-)I'm wondering,... |
