A good SE guitar amp transformer might be 7-10H (assuming a 3-5K primary impedance). A good SE output transformer will achieve 8-10H per 1000 Ohms of primary impedance.

Magnequest, Sowter, and even Hammond have some units that achieve this specification. As others have mentioned, inter-winding capacitance and leakage inductance can get out of control in the process of prioritizing other parameters.
