just brought a pair of General electric BA 34 A-1 monitor amplifiers, hoping to track down some schematics and convert into mic pres, the input transformers have several ins and outs 150 ohms, 600 ohms and a few other options.They have UTC transformers, Orange Drop caps and what appear to be germanium transistors. No Power supply needed,
any help greatly appreciated
 
They have ADC transformers rather than UTC, and are really not suited or designed for mic pre use.  They do have a lot of gain.  I don't have a manual, but they are pretty basic and should be easy to draw out.
