From BBC. Euro RCA 9285C Mic pre's. Have never been able to find a schematic on these. They do work with about 62 dB gain.
Sound nice and quite. Has UTC input an Langevin output. Would make a really nice rack pair. Comes with the Jones plug in/ out connectors. The adjustment on the chassis are labeled "Volume" and "High's". Tubes: 6072A + 12AY7 + 12AY7. each module.

Have been looking for 2 years. They are from RCA UK. Pretty simple 6072A circuit.

Quite possobly the same as the ones I have  which use Parmeko (from memory) transformers.  Although mine aren't mic pre's they a tape playback amps.
