The input stage of the new product inherits the architecture of the 610T model, using the ECC83 tube for voltage amplification. The ECC83 output is buffered by bipolar transistors, which allows the amplifier to maximize the power reserve of the input stage and preserve the best sound qualities of the ECC83.
