Single box tube linestage preamp - $3,000 used

Unfortunately I have to replace my 2-box Atma-sphere MP-1 with a one box unit due to cabinet re-configuration. I realise I will take a big hit sonically, but alternative is to replace cabinet and wife. Too expensive.
Requirements: Remote; At least 4 RCA inputs, 1 XLR input.
Not interested in ss and dont need phono - have great phono preamp. Aesthetix Calypso has replaced it, but need preamp for second system.
Amps: Thor TA 30 Mk II Class A.
Suggestions please.
