Transformerless tube monoblocks from the Canadian company Tenor Audio "Aerobatics" in lamp technology Crystal clear sound with excellent macro and micro dynamics. It's as if a veil has been removed.
Have you spent a fortune on several meters of exotic speaker cable? Have you thought about the five hundred meters of wire in the output transformers of your tube amplifier?
Output transformers are expensive components with complex windings. They are the main culprits of soft bass in tube amps. The main reasons for this are the oversaturation of transformer cores at low frequencies. In addition, about 10% of the output power is lost due to the winding resistance. An alternative is a transformerless output, - OTL (output transformer less).
