Does anyone know of a US seller for the previously discussed capacitor that improves the recording sounds on the GS

"3300pf and rated at 600V DC. 1 or 5% tolerance capacitor and it should be of the polystyrene (pref) or polyester type."

Hey Dino,
I have them. PM me your email address and I'll get a few out to you.

I was wondering, does this capacitor go wrong on practically EVERY GS, or is it still absolutely fine on some?

Hallo Dino last year j bought it in a common elettronic device store.Search in your city and probably you can find it.The voltage can be 600 volt or high.My capacitor is a 2000 Volt and work fine ....the most important value is the capacity : 3300 pF.

Kev told me that they dry out over time. So its possible that yours can still be good but if you intend to do some recording I would change it. When I did it before replacing it the recordings were muffled with no high end. When I replaced it the highs were crystal clear and it sounded like it did when I first got it. I initially thought that the problem was the heads going.

If someone can post a step by step how-to with pictures it would be greatly appreciated. Kev's posts were great, however there are a few details left out....such as getting to the capacitor in the first place.

I changed a few and posted a couple of photos on the topic "Recording with the GS1200" back in December 12th 2007.

Hope its of some help.

Graham.

Graham,

Thanks, that's perfect. I don't believe I ever saw that original post....must have been busy that day back in 2007.

Here's a link to Graham's thread, along with another capacitor thread.

Let me say many thanks to Alan Rik ! ! ! !

I agree with Doug. Graham's post is helpful as is kevin's original one, but I would love to see a picture or two where someone puts a couple of arrows to the capacitor points on the board to make sure there can be no mistakes, as I would hate to screw up...Mainly because the wires coming off the edges of the new capacitor in Kev's post don't look like they would reach the same spots as the old capacitor, so it would be great to see a close up of how it looks once completed....

first let me say that i think every purchase of a used GS really should come with a one year subscription to phone support to a personal GS expert because seriously every time you turn these things on there can be a new problem...I was deciding to change out that capacitor thanks to the help of Alan Rik who provided me with new ones, when I watched a movie and noticed a new audio hum -- as I turn up the audio there is a crazy squeal like feedback....

OK so back to the first issue...I changed the capacitor but I may have to do it again...Calling electronics guys Look at my final picture. Does the capacitor have to sit closer to the board?

Here are the issues I noticed when changing this
1 - Getting the old capacitor off was not too difficult, but getting the new one on was very tricky finding the little holes to stick the connecting wires through....My guess is that this would be extremely easy if the board was not still connected, but with it connected it becomes a game of skill trying to accomplish....The other thing that concerned me was how do you avoid scorching the board when trying to disconnect the old capacitor? As I was heating it up to pull off it got quite hot before it would budge and i was worried I might damage the board (perhaps I have?)

So the new issues i am dealing with are
1 - Should I try and re position the capacitor closer to the board and if so why? what difference will it make?

2 - What would cause the feedback squeal when simply turning the volume up while watching a movie?

I feel like I am still frustrated with the GS but now almost more than ever i feel determined to learn as much as I can about the machine from the experts because it seems like the only affordable way to own one of these is to work on them yourself, because I sunk close to a grand into repairing the previous one, which doesn't work any better than before I spent the money..

To solder/desolder: Do NOT use a soldering gun. A small soldering iron(45 watt max.) works very well. To remove old
parts, be sure the tip is clean and hot. Apply heat for not more than 3 seconds. I use a "solder sucker" to remove the solder. It also helps clean out the holes. A "hat pin" will
also help.
Use 63/37 rosin-core solder on all electrical circuits.
It goes from a liquid to solid faster. It's usually best to mount the electrical parts close to the board. Long leads may pick up stray magnetic fields. It just looks better.

Bruce, OK yes I have a 30w soldering iron (not gun) with a nice sharp tip, so I will re-do the capacitor closer to the board, and could you please post a link to a recommended "solder sucker" as I will get one.....Thanks for the help

Dino: I got my "solder sucker" from Radio Shack several years
back. Was in Rat Shack last week and they had some on display.
Good luck with your project.

Hi Alan,

just sent a PM regarding these capcitors...

Thanks

Solder wick or braid is every bit as useful, if not more useful than a desoldering pump at quickly and effectively removing solder from a join. [Wink]

I want to replace the recording capacitor on my GS1200 but don't know where to get one, and I cannot see from any of these posts exactly where to solder the ends. Can anyone help?
