| Panasonic VT50 What I don't like about Panasonic TV is that digital audio output is automatically set to 2 channel with NTSC (no longer broadcasted) and 5.1 Dolby with HDTV. My DAC does not work with 5.1 Dolby and there is no way to change it on Panasonic TV (no... | |
| The Night Air AM stations have to reduce power at night per FCC regulationshttp://www.fcc.gov/encyclopedia/why-am-radio-stations-must-reduce-power-change-operations-or-cease-broadcasting-nightI've noticed, listening to AM station, that at about 6PM signal rapid... | |
| What value cap to bypass power supply cap? I'm not sure why you need sequence of capacitors. It would make sense if you got fast and slower caps but your proposed caps vary only by value. I'm not even sure you need any caps. My vote, as I proposed before is just one cap of 1uF at the ampli... | |
| What value cap to bypass power supply cap? Dave, thanks again. I found nice drawing that shows how rectifier diode behavior introduces EMI:http://www.powerint.com/en/community/papers-circuit-ideas-puzzlers/circuit-ideas/careful-rectifier-diode-choice-simplifies-and-Also notice at the "VDC ... | |
| What value cap to bypass power supply cap? Dracule1, the only purpose of this scheme is to increase wire current delivery since capacitors are charged in narrow current spikes of very high amplitude. You can connect them in series but be sure to use as thick wire as possible and to connect... | |
| What value cap to bypass power supply cap? I would connect 12 capacitors parallel cap #1 to #12 to connect back to #1 (form circle). Now connect rectifier's output to cap #1 and load to cap #7 (opposite side of the circle). High frequency bypass cap should be, in my opinion, at the load to... | |
| What value cap to bypass power supply cap? Dracule1, 1% cap won't do much to reduce ripple but will deliver current when demanded during high frequency transitions where main caps is too slow (inductive). It will also work to suppress high frequency interference. Imagine that high frequenc... | |
| What value cap to bypass power supply cap? Dracule1, no I would not recommend Mundorf for AC line filter. What I meant is that all your caps are most likely connected in parallel and then to the amp's circuitry. At the input to this circuitry I would put 1uF cap. When you connect caps in p... | |
| What are your general thoughts of B&W speakers Manitunc, That was exactly what I read in the post when somebody went to buy B&W but listened also to Sonus Faber. He felt that B&W were more "impressive" but left store with Sonus Faber. | |
| What value cap to bypass power supply cap? Thank you Dave for good word but I'm only trying a little to repay all great thing I learn on this forum. Almarg is is the one to be praised for sharing his knowledge and constantly helping people. He is pretty much a guru for all technical things. | |
| What are your general thoughts of B&W speakers I remember Atmasphere making comment about 802 drivers. Midrange is 8 ohm but woofers total is 4 ohm at lower sensitivity expecting amplifier to double power. It won't happen with tube amp. It sounds like it is better suited for SS amp. | |
| What value cap to bypass power supply cap? I'm not sure why you need to bypass each capacitor. Why not use just one 1uF cap at the PC board entry. M-Cap like that should be most likely around $20. | |
| What value cap to bypass power supply cap? No, you most likely don't have to worry about ripple. Film caps of equivalent capacitance have much higher self resonance point and much lower ESR than electrolytics.Capacitor that has better frequency response offers low impedance at higher frequ... | |
| What value cap to bypass power supply cap? Dracule1, I speculate that main reason to add bypass caps is to improve frequency response and to lower the noise. To combat ripples you need to increase main capacitor and/or reduce its ESR.As for self resonance - you want it as high as possible ... | |
| What value cap to bypass power supply cap? Dracule1, I don't think so. Looks like you got great stuff there. I second 1% minimum recommendation. |
