[Restoration] The King of the Jungle: Aaayihiah-Yihi-Ahauauooooo

No time...sorry...

you are definitely excused, andré!

[Etienne MacGyver]

Okay, i tried to create another visual:



i think its easy to understand now ?

ps the green wire represents the ground, and should be connected to all metal parts in the cab.

[Superully]

picture isn't working for me, etienne, sorry!

[Superully]

took a new photo and added some labels



here's a cloesup of that "line filter assembly". note that the only thing left from the original setup is the fuse and that there are two wires soldered to one of the pins. there's a third wire (the white one, labeled b on the first picture) which isn't connected to anything. i guess it has to be soldered on together with the black wires. please also note that there is no power cord going in anywhere, it was already missing when i got the cab. where / how do i have to connect the cord?

[Etienne MacGyver]

I think i fixed the pic, that explanes everything 

the white wire connects to the linefilter 

[Superully]

i'll need something to drink first

the white wire connects to the linefilter 

but on the original shinobi setup there was no line filter present anymore ...

[Etienne MacGyver]

but on the original shinobi setup there was no line filter present anymore ...

Looking at the condition of the cab when you got it, it does not surprise me 

the cord was connected to the white wire, and the other wire form the cord to the "empty" terminal on the fuseholder

anyway, follow the picture , and you are compliant to the original schematics

[Superully]

alright, this means i will have to use the line filter setup and therefore get a new 230v varistor - which brings me back to my original question: which varistor do i have to by from rs online?

[level42]

I think you can forget about the filter altogether since you're using a switcher. Just MHO of course.

[Etienne MacGyver]

Yeah, that was my idea too, but since its in his bracket might as well use it

I think by the way that it will work just fine without that varistor..
(please correct me if i am wrong   )

[level42]

Yup, leave it out....the mains in Europe are a bit cleaner compared to the US I bet anyway (no wooden poles here)...although you'd be surprised what kind of "mess" is sometimes on power lines...we once had a BBC recorder checking mains power in an industrial area. It had a printer and printed anything that was "off the chart". Peaks of kVs existed ! There was a business next door that had a huge electrical crane causing this problem.

The reply from the power company ? Hey sir....do your lightbulbs work ? Yes ? Well than it's good enough for us !
Which meant installing heavy filters and UPS-es....

However, switching PSU's will "eat" a lot of this rubbish and handle it....if they are of good quality and designed well...

[Superully]

so basically what you're saying is leave out the varistor (remove the blown one from the circuit) and be done with it?

[level42]

Yup.

[Superully]

another question: once i have removed the varistor, can i simply connect the line filter to the main power line without blowing the filter itself? it says 115 / 250 V on top, so does that mean it can handle any kind of voltage?

[Etienne MacGyver]

no, it cannot handle any kind of voltage, it can handle voltages between 115 and 250 volts

but i guess that is what you mean  

higher voltages will probably blow it 

[friday joking mode on]

you can even leave the varistor in place, its already burned out  

[/friday joking mode off]

by the way, i specified the fuse by recalculating it from 110v 3 amps to 220v 1,5 amps

that value is taken from the original schematics (original powersupply and monitor)
I dont know what the new setup is going to draw from the powerline, so it could be that this value is not sufficient.

I guess the only way to find that out is to check the amount of current it is drawing when you start it up later..
