Sound with the sufficient elegance of Europ

AD1/AD-1M Single Stereo Poweramplifier　A-06-3

- Single amplifier which adopted AD1M which reproduced famous Europe vacuum tube AD1 in the present age

- Adopt the 2 steps of single amplification amplifier system which pulls out the charm of an output tube to the maximum extent.

- Adopt a long-life life and quantity reliance vacuum tube C3m as a drive tube, and realize the clear sound covering all the zones.

- Adoption and a clean and energetic sound were realized for the current regulator circuit in the power supply part of driver tube C3m.

- Side contact type Europe type vacuum tube AZ-4 was adopted also as the rectifier tube.

The feature of the Europe sound was pulled out by unifying all the vacuum tubes into made in Europe.

- Adopt the socket made from inhouse Teflon and the socket made from ceramics which are evaluated highly by highly efficient high reliability.

- Adoption and unreturned composition drew out the feature of AD1 for the self-bias type circuit so that precious AD1 / AD1M vacuum tube could be used being stabilized.

- Equip the ammeter which can check the current of an output tube at any time.

- Adopt a highly efficient polypropylene film capacitor as many part of capacitors.

- All transformers are distorted by adoption and the combined use with a Teflon insulating paper in the original cut core transformer of the high-B type which was excellent in the performance, and it realizes outstanding sound with little admiration.

- The timer relay was inserted in the grid of an output tube in order to lose the abnormalities of the bias voltage to the grid circuit of the output tube produced at the time of a power supply injection. It enabled this to use it in comfort over a long period of time more.

- Adopt the original pin jack of our company of chromium copper adoption as an input terminal, and adopt the speaker terminal made from pure copper as a speaker terminal.
