Does anyone know how to get rid of colour spots during playback?????? THEY DRIVE ME MAD!!!!!!!

Colour spots during playback????? What are you smoking while you watch your discs? Okay, seriously - I hope you're not getting tired of my replies, but I've seen 3 different cases of "colour dots". If it's mainly noticeable wherever there's a change in brightness, it could be the stylus (I think I may have mentioned that on one of your other posts, if I'm not mistaken). But if it's little spots that look similar to static on a TV set tuned to a dead channel, it could be a problem with the discs. This was the most common problem in some discs that I had that went through a flood. I also once had a disc that had been exposed to extreme heat, having some warpage and apparently some microscopic surface distortion, because the picture was plagued with thousands of little colour speckles. Other than that.....well I just don't know. Hopefully some other folks know, and will post something.

I was just thinking - are you using an SFT-100 (or perhaps some SGT model or and SFT/SGT equivalent)? If so, are you talking about the little spots that just flicker randomly here and there at first, but start showing up more and more until there's dozens of them towards the end of the side? I guess I haven't paid much attention to those until watching some videos after reading your post. For some reason I don't remember those when I was growing up, but then again we had our player hooked up to an old (I guess not so old at the time) hand-wired vacuum tube RCA TV with twin lead inputs, so if the spots were there, I probably assumed it was the TV at the time. But I figured I'd let you know that after recently getting an SJT unit working, I found that it does not have those spots, and the audio has much less noise on the SJT models (probably on the SKT models too). So if you're using an SFT or SGT, you may want to consider an SJT or SKT (if you like woodgrain, the SJT-300 has it on the sides, though not nearly as much as the SFT-100). I'm curious as to why there's a difference, so I'll be comparing the circuitry in the near future to see if it's possible to modify the SFT/SGT circuits to have the noise reduction of the SJT models.
