All transformers are tested in real working tube amplifiers before shipping.
On request we can make different primary /secondary impedance ratio or secondary winding for 4/8/16Ω.
For further technical info/ questions, communication is always welcome.
Tube amplifier projects and related circuits use high voltage and contact with high voltages can cause serious injury or death. If you are not experienced with high voltage safety and working with high voltage, this is not the project for you and you act at your own risk and responsibility.
