Do you think I colud change the transformes of the ML52?

Maxy, the November issue of TapeOp has a procedure for swapping out
the transformer in the Oktava ML52 for a Lundahl 2911 ribbon mic
transformer, which are around $60 from www.kandkaudio.com. They're
square so they don't fit into the round hole the Oktava's transformers
fit in, but you glue them down in the cavity.
