@@MariusHiFii yes ,kind of,what would you choose in your amp 4 coke cans or 20 small? are the bigger ones better than the small ones?cheers
Beautiful question and fastest answer is depends! This depends is leading to a very long discussion, practice, calculations and tests. If i will design my circuits ps, tuner, amp, pre amp, crossover...i will choose more capacitors but for the moment i m focus on my restoration and i like to keep same inside layout interior (so big caps here to fulfill original suport dimension). Sometimes for big filter caps i m adding a small capacitor in parallel for filtering high frequency... Option for more capacitors in series or parallel: - in series...higher voltages - in parallel - lower esr - bank of caps can have a more friendly shape - redundancy - better disipation of heat Conclusion - each approach has its benefits, and best option may vary based on application. I m waiting your opinion also, which option you choose, what you prefer? Thx ! Cheers!

Hi Catalin, thank you for commenting and appreciation! Stay tuned, new videos will be released! Cheers!
ai mentionat la sfarsitul videoclipului ca este la 220v si ca trebuie sa.l ridici la 240v ,poti sa spui de ce?mersi
Hi, thank you for this good question. Ideea is very simple, inside of this unit is one transformer, transformer have to sections - Primary and Secondary. Primary side is connected to wall socket 100-110-220-240 volts and Secondary contains all secondaries windings designated for unit components. Transformer he is doing also the galvanic separation. To understand better we have to use a mathematical representation formula : Vp/Vs=Np/Ns Vp - Voltage on primary winding - 100-110-220-240 V depends of region. Vs- Voltage on secondary winding - lets say 24 V Np - Numbers of turns on primary winding Ns - Numbers of turns on secondary winding Now lets have 2 examples: Example 1. - Vp - 220 V ; Vs - 24 V ; Np - 350 turns ; Ns - 38 turns. (mains 220 volts / transformer set to 220volts) Explanation - this is the situation when you have the unit connected on mains of 220 Volts and output of secondary winding is 24 volts. So far so good. Example 2. - Vp - 240 V ; Vs - should be 24 V ( IT WILL BE ?) ; Np - 350 turns ; Ns - 38 turns. (mains 240 volts / transformer set to 220volts) Vp/Vs=Np/Ns = > Vs=vp x Ns/Np => 240x 38/350 => 240 x 0.1085 => 26 VOLTS Explanation - this is the situation when you have the unit connected on mains of 240 Volts , transformer primary winding is set for 220 Volts and output of secondary winding is 26 volts - > and you see, the voltage on secondary windings are increasing !!!!! To correct this , you have to change the setting of Primary Winding, when you change from 220 to 240 you will put in circuit more turns of winding result modifies Np - number of turns on primary winding. I hope it will help you my explanation. If you consider is necessary to make a video with more details don t hesitate to ask. Cheers and stay tuned, more videos will be released !
merita 3000$? sau in banii astia mai bine te orientezi pe ceva aparate noi?
@@I-tg4dr hi, thank you for comment! Depends, some persons they have on their collection, some of them listening every day on this gears. If you are looking on market you will not see so often this machines that means people take care of them. For this vintage gears you need time to time to make some adjustments, cleaning...and so on. You can compare with an old car, more or less is same. From my point of view i prefer vintage stuff 60's-70's. Cheers and stay tuned, new videos will e released!

Hi, is not for sale, thank you !
Hello Marius. Nice job here ! I've just started to restore my SA8100 yesterday and I have a question for you: when recapping all the PCBs did you manage to do it without unwrapping the cables connected to them ? Cables seem pretty short and tight, I was wondering if I should desolder the pins ? (rather than unwrapping the cables as I read it is not good to re-wrap the same cables as they've already been coiled). Thanks in advance, Benoit.
Hi Benoit. Thank you for your appreciation, is helping me and the channel. About SA 8100 congratulations is a good machine, well built with enough power. With restoration space you have to pay attention, usually, i m not touching the wires, but sometimes is necessary and i will write some possibilities: * desolder pins is the hardest method for me - is very hard to realign all pins on boards flyng around. * unwrapping and wrapping back is most convenient method: - if you have enough wire you can do that very nicely. * wrapping back if is not enough lenght is not possible so you have to solder remain core or to replace cable with new one between that to pins. My method is to use wire wrapping and for power supplies, i like to solder the upper part of coil - because of high current there. I have cables on stock from donor devices , is presented on attached video : czcams.com/video/FhUCu10DuU4/video.htmlsi=VZXaeLzRDI9Zpb6- This is how i m doing, wrapping tools used are made by me but you can find them on Mouser. Cheers and enjoy your restoration. We are waiting feedback!
