Default Amp2 from 41Hz with +/-60V supplies

Has anyone used the Amp-2 from 41Hz.com with +/- 60 V dc supplies. If so how did it work out ?
Additionally did anyone run the board with 4 power MOSFET's per channel ? What other parts were changed ?
There is some info on upgrading the Amp-2 module on the 41Hz.com forum , but I wanted to know details from someone who has tried it.
Thanks.

Since no one has replied I guess it means that no one has tried any changes on the Amp-2 kit from 41hz.com .
That is really surprising.

I plan to use two pairs of STW38NB20 per channel and make the modifications as Jan has suggested on the 41Hz forum.
Maybe +/- 55 volt supply . But all this only after several weeks. Real world work is pretty intense right now. Meantime I will collect all the extra parts that I need. I already have the first revision board.
Cheers.

I know this thread is pretty old, but you think it would be possible to run Amp2 with 3 12V SLA batteries in series ?

It's pretty likely - you can know for sure if you find out what Tripath chip is in the Amp2 and check what the minimum rail voltage is. Depends on if it's single-rail supply friendly though. The Amp11 can run on batteries like that.
