I would ask this question at one of the OTL forums. ASOG (atmosphere OWners Group) or at Transcendental Sound w/ Bruce Rozenblit. I have his tube design book and he made a point of saying that OTLs are "fast" and that they need the proper front end to really work well. I do not have an OTL so I can't give you any direct info. He has a nice little pre called the Grounded Grid. You might take a look at that.
Also there is a guy here at Agon called "Tubegroover" who has a lot of direct experience w/ OTLs. Maybe he will chime in or you can email him and ask. Nice guy and sure he would give good advise.
Cheers,
