3.5K for tube 300B
This 300B single-ended output transformer uses British amorphous high-grade C-type iron core that has a unique advantage, especially when he static operating point is 80ma or below , it can give full play to the advantages of the output transformer. After actual measurement and listening, the voice is very vivid, clear, low-frequency tension is very balanced in three bands, excellent permeability and atmosphere feeling
Using high-quality enameled wire, lamination process, CNC drying, vacuum impregnation, well-designed 8C structure, to design to a perfect coefficient.
It is a better choice to tube amplifier audiophiles.

2.5k for tube 2A3
Vacuum tube 2A3 is a mysterious direct heat tube. Many audiophile use this tube as the end of the life. Because of its linearity and internal resistance, everything is not inferior to the famous 300B tube except the power. More tube audiophile do not hesitate to purchase an expensive British Rhode full-range speaker, or high-sensitivity horn speaker, etc. in order to complement the weaknesses of low power only. The reason is very simple, 2A3 is easier than 300B to make a good voice, because 2A3 drive signal is only need 40V, lower the threshold for the boost signal of preamplifier, and the output load impedance is only 2.5K ohms, and then the output design is also relatively easy to 300B. We special design the output transformer for the vacuum tube 2A3 now with C type structure.
