Croft Integrated versions.

The Integrateds have a passive linestage as there is no room for an active buffer stage valve as in the 25 pre-amps. (N.B. Some sellers websites claim the Integrated is a Series 7 and 25 in one box…)
That would make sense. I looked at the Stereophile review but it's never made clear in that.

I had the micro-basic and the Series 7 for a short while but the Series 7 kept blowing fuses, did not like the speaker load. I kept the pre-amp for several years though, it was fun with vinyl.
