Posted January 6, 200916 yr I built this amp from scratch about 5 years ago. I also designed everything but the output stage... I weighs almost 100 lbs. It is a pretty sweet amp, it still runs like a champ day in and day out.... Class AB, 100wpc into 8 ohms, 200wpc into 4 ohms and 400wpc into 2 ohms.....So, I went ahead and cleaned up some of the crap I did about about a year ago converting my amp for 230V and adding grounding options...I added a 5 position barrier strip with selectable jumpers on the input side for setting up the primaries of the power transformers for either 115V or 230V.... I also extended the primary wires about 10" to reach the barrier strip.Next I added small toggles to select either chassis ground or float for each channel on the RCA jacks.... I haven't needed to use this feature, but it is always nice to have. I also added a serious ground lug to the back and ran it to the star ground... I doubt I'll ever need that also, but hell, who cares....All politically correct audiophile wiring, of course.... I even used silver solder (total waste for power wiring but, hell, this is my statement amp so who gives a shit...)
January 6, 200916 yr When do they go on sale? Thats some serious power for a home built amp. If you dont mind sharing what was your total cost to build it?
January 7, 200916 yr Author I think it set me back almost $2K. The chassis was almost $500 with all the aluminium (that was over $100), stroke-sanding and anodizing...But to buy something like this new would be at least $5K+, so it works out in the end......
January 7, 200916 yr That is awesome. I have to ask, though, where did you learn everything you know?!
January 13, 200916 yr Author Thanks for the comments. I wish you could see it in person, the pictures make it look like ass....I just ordered a pair of the 1000 watt Dayton rack-mount subwoofer amps to power my XXX18s. That is my substage in the house...I am going look into a Krell KRC-2 (used) premap as the last bit of the system, other than a new Blu-ray player....
January 13, 200916 yr what kind of speakers r u running that need 2 XXX18's to keep up with the bass?
