This i find odd, i used to own the previous pre/power , it is a 3 box affiar, and certainly IS made by heybrook, i was going to get it serviced, they was happy to undertake this job, i chose not to in the end, but it certainly WAS heybrook that made mine, inside some of the large caps even had ''heybrook'' printed on them ?not sure who originally made the amps, but it wasn't Heybrook.
this is almost identical to the 3 box i had, they used a slightly different font on mine tho, i MIGHT even have a photo somewhere....The amp is ok though..But, a bargain was missed in the DJ section a while ago for a full Heybrook stack:
