here's the diagram, new link, work 100%

here's the project, http://uti-zadar.hr/quad/25wamp.htm
if you look at the pictures you'll notice the coil is wound around a big resistor, so it must be R23, which is 5W, and not R17 which is 0,6W.
i guess that's clear now.

but one other thing
where is R7, i don't see it anywhere on the schematics, or the pcb, yet it it listed in the parts list. i guess it's a typo?

and one other thing :) regarding the capacitors. i bought poly capacitors instead of MKT capacitors. will they work ok, what's the difference between these two types of capcitors?

hope you can answer :) cheers
 
It looks like the part numbers on the PCB do not match those on the schematic - BUT there is a Parts List on the website, and the part numbers on there are correct.

I would just follow the parts list and ignore the schematic. You may want to print a schematic out though and put on the right part numbers, in case you have to troubleshoot it. I'd e-mail the author (original page is http://hjem.get2net.dk/webaudio/25w/25wamp.htm) and tell him.

EDIT - the part numbers on the Postscript version of the schematic ARE correct, just the image copies on his website are wrong.
