A doorbell transformer , if it's an EI transformer will have a split bobbin and no airgap . Hence distorted bass and no top-end . If it's a toroid , it will have no airgap and play ok in the HF but have distorted bass unless cap-coupled . Add a choke for the anode load , plus a cap and the costs go above what you'd pay for a basic output transformer . You could scrimp and use a cheap PSU choke as anode choke and a line matching transformer but this is purely an acedemic excercise in attempting to save money rather than build something decent-sounding , especially when there are those inexpensive Edcor transformers out there .
