All set this end for another experimental adventure, in fact the stream links are active now and will remain valid till midnight GMT.
That annoying spike in the spectrum of last weeks webcast at 19.5khz appears to have been introduced from inside our iMac Classic better known as as Dewy and is either a D2A issue or fan noise on the supply upsetting the internal op-amp.
Reluctant to go into the case and chase it down as I have only ever been inside an Imac classic once before and that was with the aid of a hacksaw, those cases are not exactly easy to open up...maybe it's just me lol
Starting off with some pre-recorded tracks whose playback quality are known beforehand and we will see how they sound to the rest of the planet. Later on we will engage Dewy again with some filtering and see how he behaves.
