    Make your PC Power supply last- 73's de Edd

    Thanks Dave, some very good advice. I haven't got a problem with a power supply. I am looking for confirmation on where the 2 caps (secondary filter caps) are. Edd is not suggesting putting an extra cap on a dodgy cap, he is suggesting putting a second cap on a good cap to increase the...

    Make your PC Power supply last- 73's de Edd

    After some investigative reading up (have never looked at a SMPS) am I correct in saying that the 2 caps to be doubled up are the 2 little black ones next to the smaller coiled copper whatchamacallit in the photo below

    Design bass amplifier

    Yep. My common sense says: Sub woofers are big mothers in a box. 6" Speaker is something you find in a car door = mid range

    Denon AVR-1912 E2/EA

    Hmm. Sloppy design work by Denon or purposely obfuscatory? Whichever, I'm out of my depth here, need somebody who can make sense of this

    I am only on page 30 of Mr Horowitz's "Art of Electronics". so identifying a secondary filter:eek: = not possible

    Make your PC Power supply last- 73's de Edd

    This post by 73's de Edd deserves better publicity: ASIDE . . . .Hear one and all . . . . . On my computer power supplies, an initial task is to take the secondary filters and use two capacitors instead of the single ones. This done by stacking the second one vertically above the initial one...

    Denon AVR-1912 E2/EA

    I noticed that the caps are numbered more or less consecutively on a page eg. C6XX will be on the same page. I think you're right with the 1712 inference, but to find out why they are there we need to figure out where something like "To Digital Connect" leads us I have managed to find C515 on...

    Ok C515 on pg 120 of 196, bottom left hand corner. Look at ref line A to O at the bottom of page. Between C and D, right above the division between them.

    Denon AVR-1912 E2/EA

    Yep 640 and 641= 2W 631=1W Try to stick to the same wattage as size wise then the replacements will fit nicely. If they run hot you can then shoehorn a higher wattage replacement in. Having said that I was surprised at how hot they can run quite happily.

    Denon AVR-1912 E2/EA

    Strange, on page 114 of the manual I can see a resistor in each line, R808 and R814

    Denon AVR-1912 E2/EA

    All I can add is have you checked those 470Ω resistors in those lines?

    {computer}: How to add a monostable to PC PWR/Reset button?

    Dave Second using a small SSD as bootup disk. Works great. I also use Malware and AVG, happy with them. But I'm not saying temp disable, I'm saying switch off the setting that says scan during bootup

    {computer}: How to add a monostable to PC PWR/Reset button?

    Sounds like the AV program is set to scan during startup.I would switch that off and let the AV program scan sometime after boot up. If the computer stays on overnight then the wee hours of the night is a good time for it to do it's thing

    {computer}: How to add a monostable to PC PWR/Reset button?

    Is OS Windows, Linux or rotten Apple? 6-7 minutes is too long. See if you can activate something that shows you on the screen what the computer is doing/loading. I think it is hanging on something.
