Distortion on playback
One of the commonest causes of distortion in earlier Pioneer players was the failure of the buffer ram memory, which used to be a separate item. Track search, skip eye pattern etc all looked normal. Audio sounded like a badly worn 78, very distorted and with a constant crackling/scratching. Replacement cured.

Damn, Dram!
I recon so. Saw a few Pioneers that suffered in that way. Didn't get to read all the posts so missed your suggestion regarding dram. That's where my money is!

Might back up the DRAM chip problem then.

Hey
I have been following up on this thread. I am cheering for you.🙂.
I might be able to help.
I have quite a few 4264-10 and 4264-12 (or maybe 4164-15) laying around (since the old commodore 64 days) these might be very similar to what you are looking for.
I'm not sure if these might help, maybe mooly or someone can tell us.
let me know if i can help you in any way...

Hi, Thanks so much, I do hope that I get it fixed, I have once been to Haifa many years a go, magical place indeed.
I will let you know on the chip front, not sure if similar models will suit. Maybe someone else could advise.
Thanks again.
Dunno if they would be the same or not... the 10 and 12 might relate to speed, but just guessing.
Couldn't find any info on those quickly. It's possible they would be OK. Any letter in front on the number ?

Hi, I am not sure if the PMs are getting to you, but can you please let me know what is going on, if you cant get the chip to me for whatever reason please please let me know ASAP, as I need to source another one.
Thanks 🙂
I apologise if you are very busy, and dont feel you have to supply one, just need to know either way.
Thanks
Graham
I think
Mooly is right.
I also think the suffix refers to speed, but i'm guessing too.
I have attached a picture of the chips I have. please let me know if you need any help regarding these chips. As i said, i have quite a few of these, and i don't think i will use any soon.

The Philips one is a 4264-15, the 4164 I don't think ? would work as the RAM is organised differently... I am not 100% sure on that though.
4264-12 you would have to try it and see I guess.

poynton (Andy) is very kindly sending the chips to me (sorry for hassling you Andy)
So here's hoping. Thanks to liquias for the offered help as well with the chips, and Mooly, who has been a great help
I do hope that it works, so that I can leave you lot in peace 😱

Just waiting on the post then... should be a decent player hopefully... something to mod and tweak.
