Massive 6 Channel Amp based around the LME49830 chip from TI/National.
I'm moving and this thing is not coming along! Free to anyone who wants to pick it up - it is heavy. It is currently working, except that I pulled the power switch from it. I think I've already packed the schematics I was using, but it is very closely based on the manufacturers suggested design.
I designed and built this myself several years ago, and it has served me very well, and been totally stable. I wanted something with excellent performance and not power limited. In total, the amp should be able to do 700W continuously, and possibly 200W peak on a given channel, but I've never driven it anywhere near that.
It has a separate power supply with +/- 54V rails. The transformer is 1200VA, and massive, with 50,000uF of capacitance on each rail. In the picture, the upper box houses the amp modules. The output transistors are matched IRFP FETs. The heatsinks have virtually silent fans on them and barely warm up under normal conditions.

Previously, I use this with a miniDSP system (now removed), which is why you see only two input connectors. Internally, each module has its own two pin board connector, so you will have to do a little wiring to attach this to whatever you use it with. I recommend that only people with some DIY skills take this, as you will probably have to tailor it to your situation.
This thing is pretty heavy, the power supply weighs about 40 lbs, the amp probably 20lbs, so this is pickup only. The best way to contact me is at peglegpatrick AATTTT gmail DOOT com, I don't visit the forum often, please don't PM me.

Will you ship and do you have any papers for it with the specs
I have a Fedex account for shipping
Thanks
Sorry, I cant.
I've seen and heard this amp a few years back when I bought a Sencore LCR from Patrick, it sounded great! I don't have time for another project or I would swing by and pick it up.
Great guy too.
Thanks mate!
Have you changed your mind about shipping?
All you have to do is box it up with stuffing and drop off at Fedex and put my account number on the fourm with my name and address
Thank you
