Check the heater current however: 12bh7 draws twice current of 12au7, most trannies should handle this fine however: it is a 4w increase per tube, and most will handle the overload just fine: however checking is always a good idea.
A fine other choice is ecc99 by the JJ/tesla people : very good, better even than the 12bh7.
