Looking for a little help with my Saturn collection
I've got two Model 1 Saturns - One with a dead PSU and another with a failing PSU.
They are both five pin PAL power supplies.
Thankfully my model 2 Saturns have compatible power supplies and was able to test - they work just fine.
A lack of decent power supplies though is a bit of a problem.
Anyway I thought I had a good decent PSU in this particular model 1 unit, however after an hour of playing, powering off / restarting causes some crazy horizontal lines to appear.
You can see the lines showing up here http://www.youtube.com/watch?v=ru07hk_idHY
So I recorded it (see above) and noticed a hissing noise that the camera was picking up from the Saturn that I did not pick up.
After a few tests back and forth I found that the hissing only happens after it has been running for around an hour and will not occur unless the Saturn is restarted.
Here's two videos of the hissing noise going happening
Sadly I have no degree in electronics but would love some ideas on what could be causing this.
The camera I used had stereo sound so I ran it up and down the power supply to try and capture the source of the noise (or at least the area).
Here's a photo of the two power supplies for comparison - The first with "K461" on the transformer is the bad unit, the other is pulled from a working model 2 Saturn.
Anyone got any ideas on how to repair or a place from which to source PAL power supplies for these beasts?
