Re: 2x250 IRS2092 amp build

Probably closer to $325. The case added a lot and this can be done with a lower va torodial but the 800 was out of stock so I went with the 1000. 600 would do fine. This build was to be overkill from the start. With a home made wooden box and smaller Toroid, it could be built much cheaper.

Cool Arlis. I like what you did. Total cost + $350?

BTW, nobody made a board big enough so I make my own from plexi.

Finally got this done and playing. Very simple build. If I can do it, so can you. I used this amp modual from Parts Express. http://www.parts-express.com/2x250w-...board--320-313
with a 45va Toridial form Antek.http://www.antekinc.com/an-10445-100...v-transformer/
It was thought I might be a little HOT but all said and done it puts out 64.6 volts under a load. Whew!
The PSU uses 8 per side caps from Apexjr. 2 bux per! 4700x 8 for 37000 per rail. I read a bunch but pretty much copied Hong's. I used a softstart module I got from ebay and a unit that turned 12vac to 12dc I bought from AJ. works like a charm to power a 12vdc fan and 12vdc truck light to show its on. Case is form Parmetal and was about $100. this is destined for my theater so I wanted it to blend. Feel free to ask questions.
