Ready built and tested ELTIM-40mb Monoblock power amplifier module with preselected VS/CS/CD/VR modules combination. You can select two quality levels above.

Compared to the ELTIM-40ps version is has some extra's:
  • There is always a Voltage Regulator on board, feeding the input stage with ±30Vdc, improving sound quality.
  • On the extra CD-modules extra 2x one (HE) or 2x two (REF) electrolytic capacitors are added.
  • If you like you also could mount two serious quality (large) MKP capacitors over the powerlines there (not included).

The shape of this pack exactly fits MODU Galaxy 230x280mm cabinets. HE version fits in 80mm high, the REF version in 120mm high types.
The on board power supply is capable to deliver over 200W.

ELTIM-40ps HE version power / supply graph with 8A Exicon Mosfets

ELTIM-40ps REF version power / supply graph with 16A Exicon Mosfets

Aquire a transformer with two secondary windings, matching to the required power
as shown in the graphs horizontal bars. F.e. 2x 24Vac gives around 70Wrms in 8ohms.


Prototype picture, final versions differ a bit, but shape is the same !
