Edit to add: I bought this kit in 2015
Original thread here I also still have Creek 4040 amp board if anyone interested - the active cross over boards long gone for good profit
I just dug this stuff out of the cellar - I somehow imagined I'd make a DIY amp or 4 with these parts, but of course never did. I got them many years ago as a bulk lot from a liquidated hi-fi dealer here in Switzerland who used to service Ion kit - all NOS as far as I can see, but various bits stolen.
The single PCB with the heatsink different is labelled as an Ion Obelisk 3x power amp module, but all are the same power amp PCBs of P1062 issue 4, so I assume all suitable for Obelisk 3x's? Anyone here know for sure? No idea why one has 2k2 smoothing caps rather then the 10k of the others, all looks original soldering.
I assume the pre PCB is also from an Obelisk 3, but no real idea - its wire colour coding matches the amp PCB colours.
Anyone have interest in them? Happy to let them go cheap, especially if they get used to keep old Ion kit alive
Otherwise I whack on eBay - time to clear my cellar
Thanks, Richard - anyhow, photos;
Note RH channel output clamp missing - transistors look original soldered, think clamp was stolen - also has lower value caps;
This one was labelled 3x;
P1071.4 pre amp board - for 3x?
