Hi Gents,

This "compact"monoblock(45x21x37cm) produce about 75watt of pleasure in high power mode(8ohm).
When you don't like a high energy bill there is also a standby and low power mode(25w).
In fact i can control this amp with one button on the front.

Some details for one monoamp ;

trafo 2x18v 800va
rectifiers HFA25PB60 soft recovery dual bridge.
caps 8x 22000uF BC154
Coils 2x 2,2mH intertechniek
12x irf240(high power) or 4xirf240(low power)
idle current 6,6A /2,2A
hifizen board
grollins schematics
Pass inspiration
own interpretation

weight around 35kg(bad for your health).

any comment?

Best regards,

I see an aluminum brdge that appears to be spanning the two voltage rails... going from cap+ to cap-

I don't understand that part.

Help me out.
