FS: 2 Hot Rodded Hypex SMPS 400A180 power supplies

[supernet]

I have for sale two hot rodded Hypex SMPS 400A180 power supplies. To original product, the following mods were done:


-2 primary 820uF Samwha capacitors were replaced by 2 1500uF Panasonic EE long life 105C capacitors

-6 secondary 100uF Samwha capacitors were replaced by 6 Panasonic FM 220uF capacitors

-series NTC resistor were replaced by wire (additional soft start circuit is recommended)


All this changes lead to palpable sonic differencies in terms of less noise, enormously improved dynamic and headroom capabilites and 3D stage expansion. Take into account that life expectancy of capacitors is severally times improved too.


This power supply is perfect for use with VSSA or First One amplifier.


Price for 2 (dual mono) PSUs is 175 EUR + post costs.

As a bonus, you will get free soft start module developed especially for powering up two SMPS 400A180 modules. It consists of thermistor, high inrush proof relay and green led, which is mounted at the back of this circuit, so it can be mounted on the back of front amplifier plate. This circuit is derivated from higher powered Hypex smps 1200 brother.

It did a lot of difference on 400A180 (new caps have twice capacity), but we did not tried on bigger brother 1200A400.
