Hello.. is your part list same with MichalD part list ?
i have 3 gigaworks s750 and i will repair twos. Other one of them Zero and i will upgrade that one. I understand electronics, but not as much as you. İf you know more recent component of MichalD list than can you suggest for me? Will Digi-key send me the pieces at of list with the list ? Because I know that it does not write values on stone capacitors. This high hours capacitors more good than low esr? Because usually suggest LOW ESR Capacitor for SMPS. i am sorry my bad english please. Can you help me please ? Because i love S750 Gigaworks. |

QUOTE(nautilus7 @ Apr 8 2019, 02:54 PM) No, the parts are not the same. What parts do you need? Are you planning to replace all caps (electrolytics and ceramic)? Thank you so much for answer.. I am not sure I understand what you mean about digikey. You have to manually select one-by-one your products, put them in the shopping cart, and order them. At least that is what I did when buying from Mouser. The electrolytic caps me and MichalD used are high quality, long life, low ESR caps from top brands like Rubycon, Nichicon, Panasonic, Nippon Chemi-con. Yes i planning to replace all capasitor. i said, i have three Gigaworks s750. Already my a gigaworks it was never used in the zero box. i think it will broken at future. Other two, broken but working.. Sorry i'm 34 years old and i'm already a DJ. (At clubs since 2001) Just i know. On the ceramic capacitors are not write full specs. if Digi-Key send to me all in one packet. i cant. i hope Digi-Key send to me with list style. (That is to say that the parts are in separate packages and write the inventory code on them.) i looked MichalD's part list on Digi-Key and i dont see Low ESR Specs on Caps. i see just long life specs MichalD's part list.. Can you give me your part list on Mouser? And last. Wouldn't it be better if we wore parts of higher UF? Without much exaggeration. For example input 470uF 200V >> 6**uF 200V ? |

Replacing caps with bigger capacity ones isn't necessarily good or bad. It depends on the purpose of the capacitor.

Also you have to consider the size, because bigger caps may not fit. Also, if you replace existinf caps with much higher capacity ones, maybe you have problems with the RC time constant. In other caps like some high voltage ceramic ones, their value is carefully selected in relation to a resistance to form a snubber network to filter the higt voltage spikes created by the transformers. So you shouldn't change the value of these. Also, every low voltage ceramic cap is connected in parallel with one electrolytic. This is a trick to have low ESR value, without using high quality low ESR caps. So theese ceramics don't need to be quality/expensive ones, but anyway.

I hope I didn't forget anything... The answers were exactly what I wanted. For Digikey. What do you think? Which is better? MichalD's capacitor list or yours? Or which is more update (for parts) ? I'm a little perfectionist, so I'm undecided. I want to do it once and use it for many years. I do not know a precedent 5.1 or 7.1 device which is already as beautiful as this device. Do you know? Also i have z5500 on my saloon. Really it's sound too bad. it's a garbage. Thank you so so much. |

My brothers, thank you so much. I ordered all the pieces of MichalD from Digikey.
http://www.digikey.com/short/pp8zfm >>>> 186,41$ + 75$ DHL cargo. That part not unable on Digi-Key - UHW2A102MHD.. i buyed it on mouser 11,49€ + 20€ cargo DHL.. (you know. i will modifiy 3 S750 than i buyed all parts for 3x etc) But i not find that parts on digikey or mouser. Are these two absolutely necessary after this modification? FK26X7R2A104K CAP CER 0.1UF 100V X7R RADIAL added between TOP243Y's C and S PIN FK26X7R2A105K CAP CER 1UF 100V X7R RADIAL added between TOP243Y's C and S PIN Should I use adhesive for capacitors? Improper glue is easily spilled, but it can damage the PCB while it is scratching? Is there an easy way to remove this? Acetone Thinner etc? Because one of the devices is zero and the glue is intact. The products that are cleaned by LEX are immaculate and scratch free. I can see this on the front pages of the subject. I wonder how he cleaned it up. Does anyone knows? With a wood or plastic object? Or acetone or thinner? |

QUOTE(MichalD @ May 8 2019, 10:02 AM) Hello, i changed my part list ... can you check it?1. Yes, ceramic will better withstand heat produced from nearly heatsink. 2. You can't replace these with polar capacitors, you need to use bipolar capacitors only. Bipolar caps doesn't matter which polarity are connected. http://www.digikey.com/short/pzfn8b can i use UES1H4R7MEM? and i broken on amfi board R44 .. What is that? |

I think the resistors are functional, just scraped part of outer coating. Try measure it for resistance.

Everything plays well. 15 minutes later. Clicking sound is coming from relay and it turns off. After 5 minutes, it is getting better and playing. Problem after 10 minutes. I think he does it when it gets hot. And when he does, the green light is blinking behind him. |
