"Does anyone know what power this amplifier has that I found nothing about it on the internet"

Ok..given that it is named 'P1000',and also given the size and voltage of the transformer, and the modest size of the power supply components,(63v caps) would say it was designed to give 2x500 into 4 ohms. (hence P1000). Probably in real life would give around 2x400.

Hope that helps.
Be seeing you.

Yes, that is about right.

I´ve seen the bigger brother (P2000) here for repair and that was around 800W into 4 ohm. Those amps do use decent o/p devices, so are a cut above the usual cheapo crap - and fairly simple to repair/work on if necessary. I don´t think that they have anything (directly) to do with RAM - maybe some people who split from there and set up making their own amps based on the RAM.

The SMT underneath is very RAM as well.

They also share the same stencils at the back

Wharfedale pro S1500 vs S2500.
Not much difference really - few more fets, slightly larger TX.
