MACROM M2A.1000 torn pieces ...

[josesony68]

Hello everyone, today I received this amp, for repair, and when opened, I realized that missing parts on the motherboard ...

The capacitor C151, and another piece that I know it can not be, listed on the board as: POST1 (see photographs)

Does anyone have a schematic? or does anyone know that the value of this capacitor?

Thanks in advance.

The capacitor may have been removed by the manufacturer. The 'post' is a ground point. Sometimes they use a cup but if the heatsink won't allow that, they use a wire as you have in your amp.

Yes, thanks Perry, is likely to be as you say, (in your photo, it is clear).

The fact is that ..., when connected, no sound until last eight seconds ..., first red led (protection) for five seconds, then turns green, and when they pass three seconds is when you hear the sound ....

Is this normal? Does this type of amplifiers?
