Preamplifier with separate power supply uses the ECC 40, which is one of our
favorite tubes.
We appreciates for musicality and timbre. In a line stage preamplifier, he also uses a 76 tube that is for us, a natural, musical and transparent sounding tube, but is difficult to apply due to microphonics.
Our solution to the problem of microphonics was to use of moveable and independent extend plates and dampers.
