| Capacitor log Mundorf Silver in Oil Just a minor revision. Taking a look at the schematic for the proposed Tannoy x-over, there's also a 10uF value at the beginning of the signal path, along with a 5.6uF and 20uF across the HF and LF sections, respectively.The plan is the use the be... | |
| Capacitor log Mundorf Silver in Oil It's a 15" 3859 dual-concentric which, in the mid-1980s, was originally sold in either the Panther or Cougar stage monitor cabinet. A variation was briefly (and unsuccessfully) marketed for home audio and my partner has come up with his own design... | |

| Capacitor log Mundorf Silver in Oil I'm starting to read some of the recent posts and see that many of my comments have already been covered to one degree or another. For example, the link between Steen Duelund and Harvey Rosenberg, the Fisher EL84 amp, and so on. I was also going t... | |
| Capacitor log Mundorf Silver in Oil Volleyguy wrote, "I had noted that even one poly cap in the crossover and the sound changed to plastic..."Let me elaborate further. As mentioned above, to talk about "foil caps" vs. "poly caps" is to use a mixed metaphor. That is to say, all poly ... | |
| Capacitor log Mundorf Silver in Oil Further thoughts:While it's easy to become overly focused on one component or another, the audio system always needs to be considered as a unified whole. From the time the stylus enters the groove or the laser beam hits the pits, until the signal ... | |
| Capacitor log Mundorf Silver in Oil There's quite a lot to address here, so I may just comment on one issue at a time.In terms of materials, all caps contain two layers of foil, which can be silver, copper, tin, or aluminum. That's the material which is electrically charged. The ins... | |
| Capacitor log Mundorf Silver in Oil Thanks for your comments!I don't want to beat this topic to death, but the system used in labeling each level will always carry some sort of psychological baggage with it.As an editor, I never cared for the original A, B, C, and so on, because of ... | |

| Duelund Capacitors?? The Duelund VSF Copper is currently used as part of a loudspeaker x-over. It's the only cap that's directly in the signal path, making it very easy to evaluate.The Jensens were tried in several circuits, including as coupling caps in a tubed phono... | |
| Duelund Capacitors?? Agreed. Based on our experience with Jensen aluminum vs. Jensen copper (Jensen is the OEM for Duelund), copper foil is the way to go. We have, in fact used the Duelund VSF copper foil and can highly recommend it. If you're on a budget, forget the ... |
