The secondary of that transformer is designed for 4 Ohm and 8Ohm, but the Castanet use it for running low and high impedance headphones. Is it OK?
The transformer specs says: Frequency response 30Hz to 20kHz, and the amplifier specs 12Hz to 75kHz. Is it possible? http://www.hagtech.com/castanet.html
EDIT: I remove the schematic, since I notice that it's copyrighted. Please refer to the link above if you want to see it.

Re the transformer: Maybe its OK. Run a 10Khz square wave through the amp. If it overshoots/rings on the leading edge load it down with a resistor. If you like the way it sounds dont worry, sometimes what you dont know is better than what you do know, you know?
Hammond rates -1db bandwidth, hagerman rates -3db. The posted numbers by both parties could both be right! When you play the square waves check the frequency response with sine waves too.
