| Elrog 300B vs Takatsuki 300B tubes Thanks again, Jet. And kudos for the prudence and thoroughness that is evident in your approaches.Best regards,-- Al | |
| Elrog 300B vs Takatsuki 300B tubes P.S: A sharp-eyed reader may notice that at one point in my post just above I kind of juxtaposed EML's +/-5% tolerance with the 5.06 volt measurement Jet provided for the Sophia tube. I'm assuming that had Sophia provided a +/- tolerance on the 5 ... | |
| Elrog 300B vs Takatsuki 300B tubes Thanks very much for providing that info, Jet. I've done some fairly lengthy calculations based on it, the results of which are listed below. These results assume (as I would expect) that the dropping resistor you mentioned is on the primary side ... | |
| Peachtree Audio Nova - No subwoofer connection Good news, Jim! Thanks for the update.Another reason you may have been hesitant to accept the idea of a splitter might be the many negative comments about them you may have seen here in the past. Although on occasion positive ones do appear. My be... | |
| Elrog 300B vs Takatsuki 300B tubes Thanks very much, Jet. Could you give us a rough idea of the magnitude of these voltage changes that you see in your particular amp?I did a few minutes of research trying to find specs on the resistances of filament windings of transformers that w... | |
| Good impedance match for Precision Fidelity C-7AR Pix4work, looking at some photos I found of the interior of the PF it appears that the volume control pots may be the unsealed kinds (unless the Alps you mentioned are upgraded or different than the ones I see in those photos). So it may be possib... | |
| Thought on OTL tube amps Ralph, yes I had looked at the patent, and I completely agree with your comments.Tubegroover, thanks for the suggestion! I'll be sure to check out those discussions. Prior to this thread I had no awareness of this amp, as I mentioned earlier, so I... | |
| Absolute top tier DAC for standard res Redbook CD Gentlemen, be aware that this Saturday a very large asteroid is projected to pass us by at a distance not much greater than the distance of the moon, at a speed of about 78,000 miles per hour. If the calculations are wrong for some reason there ma... | |
| Elrog 300B vs Takatsuki 300B tubes It occurs to me that I should perhaps add some clarification to Matthias' statement I referred to just above, which I quoted in my first post of yesterday. That statement was:If an EML 300B XLS is the right choice we have 1.5A heater current at 5V... | |
| Elrog 300B vs Takatsuki 300B tubes Thanks, George. I don't doubt that what you are saying is correct in most and perhaps nearly all cases. But without knowing the DC resistance or low frequency impedance of the filament winding of the particular transformer (which would enable calc... | |
| Good impedance match for Precision Fidelity C-7AR No, that isn't an impedance issue, and I would also not expect there to be an impedance issue in this particular case. It sounds like the problem is that the combination of gains, sensitivities, and source output level(s) in your system is simply ... | |
| Elrog 300B vs Takatsuki 300B tubes Yes, thanks for chiming in, George. After thinking about your comment I agree -- the 5 volt winding for the directly heated 300B and the 5 volt winding for the rectifier must be separate, or the circuits wouldn't work properly. Thanks for pointing... | |
| Peachtree Audio Nova - No subwoofer connection P.S: Subsequent to submitting the previous post, I did find an output impedance spec for the pre-outs of your Nova 80W integrated, that spec being "<30 ohms." So, again, I don't know why it wouldn't be able to drive the sub and the amp without ... | |
| Peachtree Audio Nova - No subwoofer connection Jim, I couldn't find an output impedance spec on the pre-outs of the Nova 80W integrated. However the Nova 65SE, 125SE, and 220SE all have the corresponding output impedance specified as "< 50 ohms." Assuming your Nova is similar in that respec... | |
| Elrog 300B vs Takatsuki 300B tubes Hi Bill,The upshot of my previous post is that if no one participating here has already done so I suggest that one of the Lampi users ask Lampi if each of the various rectifiers that have been discussed is suitable for use in the Big 7 and the GG.... |
