Hi,
Yes, I've got a RAT modified Blackheart BH5 Head which I use with a home built Vintage 30 Cab. He has added a few more extras now but it's very similar to the blackhearts he currently lists on ebay. The main mod's mine has are switchable diode or valve rectifier, power scaling plus master volume, swtichable EL84 or 6VTGT output valves, and a gain boost footswitch, line out and switchable speaker impedance.
For home use I think it's really great. There are a few other forum members thathave them a well. He's now added PS1 plus PS2 options and an effects loop, plus swithable gain, an improved output transformer, so I'm sure some of the current ones are even better than mine. I've never thought about selling mine but I have thought about sending to Andy to get some of the newer mod's installed. He's a very helpful guy and if you contact hime I'm sure he will fit whichever options you want.
At very high volume mine has slightly limited clean headroom but for home use you can go from nice and clean all the way to AC/DC with no effects just pure valve crunch or overdrive.
