| Repair your Cambridge Audio 840E volume contol issues To answer some of the accumulated questions over the past few years:My unit has not misbehaved once since I published the mods with the Fujitsu relays, and I use it every day. Note I did not replace the encoder, only the relays. I also have my uni... | |
| Capacitors for HP filters in tube amps recommendations? pragmasiYou need to be cautious when recommending CGO/NPO ceramics for audio (particularly coupling not bypassing) applications. I know from experience that some NPO/CGO caps (particularly those from TDK ceramics) have a voltage coefficient of cap... | |
| B&W 802D tweeter replacement At the online B&W parts store, the tweeter for the 800D series is available as a separate part, SKU 14265:http://www.bwgroupusa.com/bwgroup-parts/index.php/bw/speakers/800-series/800d-series/803d/800d-tweet...It is priced at $1086. Not much ch... | |
| BEST fullrange speaker drivers in existence, 4"-10" diameter range, and...Go! I would check out the Pure Audio Project Horn 1 compression driver. I think its about 40 Hz to 20K. They also have the Voxativ versions (there are three, but VERY pricey). | |
| B&W 802D tweeter replacement I own both 804 Nautilus and 803D speakers. Both have exactly the same FST midrange (kevlar) driver, but different tweeters. I can tell you the Nautilus tweeter is dimensionally quite different than the diamond tweeter, and I don't think the Nautil... | |
| B&W 803D crossover caps Erik S:Last time I checked, a few years ago, Jupiter did not make a copper film cap in 47 uFd to replace that critical midrange coupling cap. Clarity cap makes one in their CSA line, but that is metallized poly pro. It is 62 mm diameter (much larg... | |
| B&W 803D crossover caps "Sorry no you confused the discussion, you said amp (see below) and I said amp and then you bought preamps into it. Most of us with the knowledge know that many sources and pre’s have much smaller coupling caps than what would be on the output of ... | |
| B&W 803D crossover caps biggy:I am currently using all Silver Gold Oil Mundorfs; either Supreme versions (TW coupling, MR bypassing) or EVO (not Supreme) versions (MR coupling), except for the bass LF crossovers, which are bone stock. As mentioned, the harshness I believ... | |
| B&W 803D crossover caps George:You miss the point. I just explained that film caps are often not an option when the manufacturer is using surface mount technology for the components. Plus, the proper size poly pro film cap will physically not fit in a 1U chassis and is e... | |
| B&W 803D crossover caps " This kind of amp cap coupled output is very rare to have. I take it it’s tube with no output transformer, but with capacitor coupling instead, I would just get an OTL myself but??"Not as rare as you think. Did you know the Bryston BDA-1/2/3 all... | |
| B&W 803D crossover caps George:Regarding parallel caps. I agree in general, except when there is no or limited choice. For example, when an Al electrolytic is used as a coupling cap at the output of an amplifier driving low impedance loads. A polypro or film cap may not ... | |
| B&W 803D crossover caps biggy:Regarding sizes. Check a website like parts connextion. Not all "EVO" sizes are the same, and the "Supreme" (black) versions are larger I think. I used the " 47 uFd EVO silver gold oil", in the white cases with gold printing. The "Supreme" v... | |
| B&W 803D crossover caps biggyThat is what I did. Silver gold Oil 4.7 uFd for the coupling tweeter; 47 uFd EVO SGO for the mid coupling cap; SGO 10 uFd for the mid bypassing cap. Whether you use SGO or just "oil" (those are aluminum metallized instead of gold/silver) is ... | |
| B&W 803D crossover caps biggy79I don't think george reads your posts carefully. You are correct, there is a 'bypassing" cap (ie one parallel to the FST driver) in the crossover network. It is a Mundorf silver gold or silver gold oil, depending on what product you have or... | |
| B&W 803D crossover caps georgehifi:I don't think I suggested there is a quality issue with the parts in the crossover, but a cheaper MKP version will not sound the same as a Silver/Gold/Oil. That is why they make the SGO in the first place. Do you even have 803Ds or have... |
