Does anyone have a headphone amp circuit diagram using a 300b tube, I wouldn't mind having a go at building one.

cheers

to drive what impedance cans?

uhm, take your favorite 300B circuit and put an OPT with the proper secondary on it... take will give you a start.

Arnold is correct -- just get some OPTs with a 64 ohm tap, perhaps a higher than normal primary, and maybe ease up on the driver -- you don't need to drive it to full output.
