Hey Mike, I’ve not used the SSL Origin but, mixed and recorded a lot on E & G series back in the 90’s. The one thing from the pictures is that the faders seem a fair bit shorter than originals… may be just the pics but something I noticed.
Have you tried Sphere recording consoles? The routinely have gear for sale. I posted a thing to the Gear talk thread a few days ago as they had some amazing gear for sale…
I know that’s mot the answer you’re looking for, apologies… thought I’d mention it though.. 🤷♂️
