25w amp

pudge667 · 16th April 2007, 07:45 PM

here's the project, http://uti-zadar.hr/quad/25wamp.htm

it says R12 is not used, yet i have a place for it on my pcb. i looked at the schematic, and i saw that Q2 collector should be connected between R10 and R17. is that correct? it's like that on the schematic just not on the pcb.
plz hlp
cheers

http://uti-zadar.hr/quad/pcb_shem_mod.jpg - my correction of the pcb
