| What exactly is a 20 amp dedicated line? Thanks Jea48 for the info. Please clarify a couple of points you made. First, is the NEC the National Electricans Code? Second, if a multi wire branch circuit is set up in the manner I described above, please explain how a multi pole branch circui... | |
| ARC Ref 3 Main Output Impedance Question Well Al, . . . if one of you techies think this could potentially affect a significant swath of owners of tube pre/ equipment, other than the Atmasphere OTL type of course, perhaps someone with the equipment and know-how will run some tests as Hif... | |
| What exactly is a 20 amp dedicated line? Jea48, do you know if it's Code to run a single 220v romex line consisting of 2 hots, 1 neutral and 1 ground into a single receptical box, with each hot powering a separate receptical and the single neutral and ground doing double duty for the two... | |
| ARC Ref 3 Main Output Impedance Question Certainly an interesting discussion. However, in my case, now that I have been alerted to the issue, the problem is moot because Tom is making a custom buffer device with high impedance balanced inputs that will sum the channels for my sub. I am a... | |
| ARC Ref 3 Main Output Impedance Question Atmasphere, do you think asymetrical loading would affect sonic quality? Not being an electronics techie, I of course have no view. All I can say is that ARC did not think it was a good way to load the Ref3. | |
| ARC Ref 3 Main Output Impedance Question Bob, why poo-poo'ed? If pure resistive, why not just stick a resister in series with the load? | |
| ARC Ref 3 Main Output Impedance Question Hifigeek, that makes perfect sense. As stated above, I expect that there will be two benefits to the device. One, longer tube life (b) because the pre will be loaded at a higher impedance level AND (b) because the load will NOT be asymetrical, i.e... | |
| ARC Ref 3 Main Output Impedance Question Bob, by active or passive, I assume you mean powered or not. FWIW, it plugs into a 120 AC socket. Tom mentioned that it has a 1:1 op amp in it -- whatever that means. I don't know if it uses a transformer.Hifigeek, 2 other A'gon posters have recen... | |
| ARC Ref 3 Main Output Impedance Question No_money, I don't know. Call Cal at ARC. He'll want to know how you hooked up the Ref 2 to your amp and sub, i.e., balanced and/or SE, and what the impedance loads of each application are. In my case, I had a double problem: (1) the imput impedanc... | |
| ARC Ref 3 Main Output Impedance Question Hifigeek, agreed 100%. I should get the connector device in about 7 to 10 days. Tom is loading the balanced input at 330KOhms, which is close to the input load of my ARC VS-115, which is 300KOhms balanced. Does that seem good to you? BTW, as crazy... | |
| HELP-Maggie IIIa's are crackling at high frequency Sonorous1: If you think the Maggies are ok, then I still suspect the amp may be clipping. I am dubious that 62 watts at clipping is enough power for the Maggies. I suggest that you borrow a high power SS amp from a friend or a friendly dealer and ... | |
| ARC Ref 3 Main Output Impedance Question Vmk & Atmasphere: Thank you very much for the suggestions. I called Tom Tutay and discussed the problem with him. Tom will build a custom connector box having stereo SE and balanced inputs and a mono SE and balanced output. The inputs will hav... | |
| HELP-Maggie IIIa's are crackling at high frequency Admittedly I don't own or know anything about Maggies, so I am not adding to the advice already given. However, your OP doesn't say very much about the ARC gear other than the model numbers. I have a few thoughts about the ARC gear. First, the V70... | |
| ARC VS-115 Amp with new KT-120 Tubes Post Break-In Update: Probably have 25-30 hours on the KT-120 tubes in my ARC VS-115. So far, no arcs or blow-outs. The sound quality continues to become more mellow and refined -- not rounded or rolled off, just less edgy on the high-end. Imaging... | |
| ARC VS-115 Amp with new KT-120 Tubes Sdgron, good shabbos to you as well. I'm not sure how much more the KT-120 tubes will break in after 20 hours. Just curious about your amp, why did you have your dealer check the VS-110 with the new tubes? Were you concerned about something? Also,... |
