| Bob Carver LLC Black Beauty Review Namikis, yes I think the main difference between the Cherrys and Blacks are transformers power rating and perhaps the power supply caps. I think for relatively reasonable expense by replacing the stock coupling caps and volume pot, you will hear a... | |
| Bob Carver LLC Black Beauty Review I have a pair of the Cherry 180s, bought when Bob used to sell them on eBay. Mine was built with some modifications...V-Cap output coupling caps, Furutech RCAs, Vampire copper binding posts, and non-captive cords. It also has the vintage pie wound... | |
| What value cap to bypass power supply cap? Hi Kijanki, I will need to think about your wiring scheme to make sense of it. I'm not an experienced DIYer.I think I will use high purity copper wiring with Teflon jacket.As for the Hyperions, I'm not sure if I can answer that question. However, ... | |
| What value cap to bypass power supply cap? Oh I see. That makes sense, but I thought you want the bypass caps as close to the power supply caps as possible? The further away the bypass cap is, the less effective the filtering, no?I thought the 0.1 microF cap will handle those high frequenc... | |
| What value cap to bypass power supply cap? Hi Davehrab, thank you for your input. When I started this thread, I was confusing several things about bypassing. Here is what I've learned so far from helpful people like you and Kijanki. Please correct me if I'm wrong.1) The 1% bypass cap recom... | |
| What value cap to bypass power supply cap? Hi Kijanki, I think what you're talking about is putting a single cap at the input as an AC line filter. That is a great place for Mundorf Supreme. People have already tried this out and got good result:http://www.laventure.net/tourist/caps.htmHow... | |
| What value cap to bypass power supply cap? They're not for preamp or DAC. They're for monoblock amps. However, there are a total of 12 of these. Still not a lot by electrolytic standards, but they are huge cans, each about 7 x 5 inches and weighing around 4 to 5 lbs. According to the desig... | |
| Does OTL pre-amplifier exist? http://diyhifisupply.com/node/808 | |
| What value cap to bypass power supply cap? Amplifier's end means where the output transformer goes to ground, I think.I'm a little confused. "Increasing main capacitance will reduce impedance but also reduce self resonance point. It might be necessary step to combat ripple but does nothing... | |
| Preamps waste of money? Mrtennis, I have a DAC that has an output tube and a rectifier tube. I have been changing those tubes to change the "flavor" of my system. Having too many tubes in a system hasn't been a good thing IME. Too much heat, to many tube failures, too mu... | |
| What value cap to bypass power supply cap? Davehrab and Kijanki, I asked an experience electronics engineer who has written papers on bypass capacitors. His response to your statement:"As you can see from above, the self-resonant frequency will vary depending on the value of capacitor used... | |
| What value cap to bypass power supply cap? Kijanki, thanks for that info. However, all my power supply caps are film caps which according to the manufacturer have ESR and inductance which are a fraction of electrolytic. I know the ESR is 1 mOhm at 10 kHz, but I don't know the inductance. A... | |
| Preamps waste of money? But getting back to the subject of this thread, I'm not sure one can ever determine if his preamp is "neutral" unless he was at the recording session and all his other components in the chain are neutral. Essentially an impossibility for most of u... | |
| Preamps waste of money? Yes Kijanki, the Hyperions have one of the best midrange of any speaker I've heard, including electrostats and ribbon speakers. Their spiderless drivers are unique. They haven't folded yet. I might end up getting a pair of the 968s. | |
| What value cap to bypass power supply cap? Thanks! That was very helpful. |
