Tony - 6.98 Sounds great!
Where are you getting the toroid? Can you find me a toroid for a low price... or 2 X 1250 watt versions?
I really want to DIY some amplifiers, but I need to use them too. Someone called me with a quote today for $600 and I laughed at him. By the end of the call it was 2 for that price, but still $300 is much more than some other quotes, and they are too high as well.

Hey, not a big deal better go for a Behringer EP2500[qsc clone] for much less the price of QSC RMX2450. Its DIY not a profit or loss business design, build it for fun if you want it. I agree toroids are costlier than smps.

Depending on who is interested - we can get them made in the States for about the same prices floating around... Between $35 - $65 per amplifier channel, and probably about the same for the rest of the boards together... I can also get them made in China, and using our Logistics company - Shipping is only about $5/k (2.2 lbs)
You're not in the US, so it doesn't really matter... but probably all 5 boards per Kg (1Kg=2.2 lbs)
Yes you can use MJL21193/94 pairs for 2KW.
Don,t worry about power supply, its easy to do, do let me know when you are going to make the amplifier, i will give you complete power supply details.

Kanwar - All of these designs need I/O PCB's, they need at LEAST one control PCB, and they need the power supply. I know how to make a power supply. But this post hasn't even stated the rail voltages. I have no idea what the input voltagers are for signal. I don't know if the control board has pots to control the volume, leds to show power on, basically everything other than a nice single channel H class amplifier that does me no good without the other parts....
So not worrying about all of the other parts is fine to say - but if you are going to build this, all your money is a waste unless you have all of that information... not to mention the fact that people like a BOM to order things, trade, etc....
I know you guys are used to the aggressive boards, but this board is mellow. You should offer all of the information or none.... When I build anything - record in the studio - etc - I have all the tools, all the drawings and ideas on hand, and all the hardware I need to complete the project.... I don't start with a single part, and pray that someone sends me the BOM, the REST of the parts, etc... It's normal and logical. For a DIY to spend $100 just to get 1 of hundreds of parts, and have no idea what the rest of the parts are is illogical and possibly a pipe-dream it will ever be finished...

Also - When I learned this stuff, there were no IC's that had dual integrated mosfets, high power BJT's, IGBT's, etc.... there was no internet... So to re-learn, I like to visualize the circuits as I know they are, not just place an IC and connect the rights wires. I didn't have software to go from schematic to PCB... and NO WAY could I order a PCB and have it in a week...
So, now - getting a PCB with no values and MISSING the NC drill path is like having nothing but a bunch of red and blue blobs to look at. What goes through, where is the signal going on side B, etc... I need to see that for my own mind... cause I want to relearn all this stuff that I forgot over the past 20 years, and also learn how to do it with the new software...
Ya Dig?

Here you go with drill file.............
Btw: You can generate drill file from gerbers itself.
You told me that you want to make BOM yourself and also what about the power supply and front panel PCB files which i had emailed you a week ago.
