Sounds like cap juice affecting something in the sound chip area. Is it coming from speaker or psu??Working with the 32MB SIMM and the 2 x 512MB VRAM too. Thanks for the help everyone! Maybe I'll start asking about a weird issue with an LCII that makes a high pitch whine - that varies in pitch over time!
The sound is coming from the speaker on the LCII - sounds a bit like an old fashioned kettle with a whistle, though sometimes the pitch is steadily increasing like a kettle coming to the boil, sometimes it’s decreasing in pitch like a bomb falling!Sounds like cap juice affecting something in the sound chip area.

No, it's not that. These run fine without the cover on (not advised for long periods but I've never had an issue doing it).It's occurred to me that I've been running the LC 475 without the cover on. I remember that Mac's like the PowerMac G5 need the case to be closed for the cooling system to work effectively - does the same apply to the LC models? Perhaps I'm causing it to overheat?
The lc ii most likey has cap juice under sound chip and other chips in the area. My lc ii made nasty noises until I cleaned all those up. Had to remove and clean pads, check traces etc. recapping only one part of the restoration..I’ve tried previously with the power supply from the LCII and it didn’t make a difference. Both have good voltages.
OK, thanks. I thought that might be the case. I don't have a hot air gun, so will probably have to live with it for now until I feel brave enough to give that a try.The lc ii most likey has cap juice under sound chip and other chips in the area.

That's one special 475! 1 GB of VRAM!!! I bet it can do 4k, yes?Working with the 32MB SIMM and the 2 x 512MB VRAM
