To-be-added power supply dedicated for EA-1000PS-1000
To-be-added Power Supply dedicated for separated type tube phono amplifier, EA-1000,
which can educe music reality and even the artist's passion engraved in records
Power supply unit adopting the large power capacity R-core transformer and directly-heated rectifier tube, 5U4G
The luxurious rectifier circuit consisting of the R-core power transformer having more power capacity
than necessary, a rectifier tube not generating a switching noise principally 5U4G and two choke
transformers of independent L/R are adopted. In addition, the high S/N ratio is achieved by adopting the
power supply circuit of the tube heater ignited by a DC which consists of the 3-terminal regulator.
Doubling the ability of the power supply
When the shorting connector of the accessories is connected against the power output connector that
are not connected, two choke-transformers and two electrolytic capacitors for individual L & R channels
are connected in parallel and then the output impedance of the power is decreased; therefore, the ability
supplying the power becomes greater.
The housing structure consisting of the chassis made of a 2 mm-thick solid copper plating steel and the
cover made of a 1.6 mm-thick copper plating steel succeeds in securing rigidity and having a good
shield performance at the same time. The black-anodized aluminum front panel made of a shaved 5
mm-thick aluminum is adopted. Therefore, the dignified finish having a high universality will never
disappoint you on the owner's joy.
