Magnequest DS 050/600 OPT replacement?

The subject OPT is employed in a line preamp with sum total one tube, a 5842 RF type. MQ is retired. I respectfully request a list of the best replacement transformers to build a matching preamp. I also need to know the cost for the replacement trafo.

Upon request I'll post the schematic which I sketched. The MQ DS 050/600 OPT has 3 output leads with 3 different gain options of about 8, 18 and 21 dB. A fixed gain of about 14-17 is OK for my application.

A couple days ago I asked MQ for the trafo specs and no reply yet.
