Then have somebody order it for you and send it to you?

Hi, DJ
Why not give ESP a mail and see if he can sort things out:
[email address removed by moderator.]

That's the best I can come up with; Don't know much about international trade..

Why can't you order from the ESP site? I don't see anything on the ordering information that says he won't accept orders from Israel.

DJ: Can't you give the circuit to someone and have them manufacture it for you? I'm sure Israel has an electronic industry - and a pretty good one, too. Maybe a friend can help?

Alternatively, build it up on veroboard? Most of the wiring is on the power transistors - which can be with heavy-duty wire directly on the devices. You may not need a PCB. These circuits may work well if you try P2P or veroboard - so long as you take care to reinforce the current paths, etc...

Also, why this particular project? If I remember correctly Rod intended this as a Sub amp and not a hi-fi amp - are you building a sub?

Are you going to be running a stack for PA or do you have a pair of terribly inefficient speakers that you're looking for such high power?

I have mid-range speakers with a 35 W RMS amp and I rarely need to crank it up.

Maybe you need some help to select a good amp design that sounds good? More power isn't necessarily better - even though there are design of 1,000 watt amps on the net - if you want you can ask me and I'll send you schematics.

But First priority should be quality? Or is it really that you need so much power....

Good to know that India is not the only country where internet ordering is a problem...

Yes, Rod clearly states that the amp is not intended for hifi, or PA use evn - only for subwoofer use inside the sub enclosure as the amp has no short circuit protection so any mishap will result in death of the output devices.

Also I rechecked and the schematic has only four transistors and a few passives that will need a PCB. Everything else can be hardwired. The reason hardwiring was not suggested is that inside a Sub there may be too much vibration....

DJ I do not think this will work well as a regular stereo amp as you want it to. Please read Rod's text along with the project. Only 3 V/uS is maybe too little....
