Alright, I figured out how to make this fit in my studio without heavy rearranging of the racks/patchbay. Its outputs could go into the front inputs of my RME Fireface 802. The combi mic/line inputs have an extra 6dB of gain but it's really clean so I don't think it will detract from the sound, compared to plugging them into the straight line inputs. And I can buy an extra 4U rack for it.
I'm saving up for it already!!! Any idea when it will be available? My next big recording session is in about one month...

This prototype is built in a modushop case. I am working with a local metal fabricator to design a 16 gauge steel chassis for this. That will take a little time to figure out if it's worth the effort and price.
This design was first inspired by the Hamptone preamp article with some changes along the way. I believe the design shares some common features as the Jensen cascade follower schematics and a garden-variety input gain stage. The most significant sonic impacts have been using the NOS General Electric 5-star 6072 tubes, using any of the NOS GE or RCA 12BH7s to drive the output, and the Jensen input and output transformers, which are definitely worth the added cost. Of all the transformers I've tried, the Jensens are special. It's quite incredible what they have done in designing them.
It's not exactly like anything else on the market, but similar true-tube, non-hybrid 4-channel preamps would be:
Your work is great, Dan. If I was good enough to make money at this, or was a wealthy man, I would certainly have a bunch!
And yes, Jensen's are ridiculous. They are of course in my Hardy, as well as some other gear I've had. They were also excellent in the Hardy-ish Hairball Gold pre's. There is just something about them.
