I don't know what happenend with those guys and their Sp1200's but I'll tell you that if you have an sp1200 and you don't know if it's had it's capacitors replaced or not you just oughta do it. There are hardly any caps on the sp1200, but they need to be replaced and it's easy.
If you don't know how to do the soldering, DON"T LEARN ON YOUR SP.
but don't spend a fortune sending your bird to Forat either.

spend 50 bucks and buy a guitar distortion pedal kit and learn how to solder with that and read a schematic. oh yeah and then you get a distortion pedal for your trouble.  try general guitar gadgets, or amz.  they have pretty good kits.  

shop at mouser or digikey or allied. they have everything you'll need
read up on capacitors on wikipedia
you need electrolytics  
somebody mentioned the panasonic FC series and those are really good
you also need polystyrenes
with polystyrenes- you are going to probably just buy whatever they have and the brand doesn't matter that much.

anyhow, this is just my 2 cents but if you had a 1970 dodge charger and you don't even know how to check the oil, well that's just wrong and maybe you shouldn't own one in the first place.  
CAPS and the floppy drive are the 2 things that you're going to have to deal with at some point on your SP. The floppy drive will die when it dies.  and that's pretty much it. replace it and get back to work.

Let your caps age out and die, ( and they should be gettiing pretty iffy on any sp1200 thjat hasn't had the service ) and any number of really serious problems will cascade from there.
rock the bells.

OK, ONCE AND FOR ALL!!!

Can somebody PLEASE paste some link's to all the correct parts we need for this?
It's like a 6 pages thread, with no direct link to the parts we need to get...

Help us just order the right parts. And then we can get somebody who really knows how to solder to do it for us.

PLEASE!

last days i change the wrong capacitors in my sp1200 and now it's really no hiss at all....

here the caps i use, are not the same brand, but are the same for the rest
http://www.allelectronics.com/mak...0-PF-POLYSTYRENE-CAPACITOR/1.html
i update this is also better, i just use the 160 volt, dunno if it could change something

here a records i made, is it in record all the time, from the first second so u can hear the small amount of hiss i have (really nothing), just a little hum on the back but it's pretty normal...
