thanks alot. went back over the values and found that whne my friend started the board, he switched the 82 and the 8.2k ohm resistors, as well and made errors in the 390 into a 3.9k and the 3.9k into a 390M ohm resistor. and used 10 ohm resistors where 10k's go. i'll replace these tomarrow and let you know if i'm still having issues.

Check your resistor values. From the photo, the 82 ohm apears to be 8k2.
That alone would make it unlikely to work.

>checked all the transistors and everything is in the way the board shows
them to be, with the tabs pointing the right way. i am using the specific
transistors that the site says to use with the metal caps. the other thing i
am thinking about is that i am powering it via 2 9v batteries that i've
connected in both series and parallel. neither made a differance. originally
i connected them in parallel with the pos. lead connecting to the +ve pad,
the pos. of the second battery and the neg. of the first going to the 0v
pad, and the neg. of the second going to the -ve pad. now i have both pos.
leads going to the +ve and the neg, going to the -ve and a jumper going form
the ground to -ve pads. sorry if this was all a stupid rookie mistake and
have wasted all your time. if i can get this working, it is intended for a
standalone rack unit. i am using the batteries more for testing purposes
before i get a power supply. i've put up some pix on my website to see if
anyone can tell me if i put something in wrong. sorry if some are a little
blurry, but i am using a new camera and still getting use to it. anyway, the
site is http://www.havensole.com/steinervcf/ please let me know if there are
any problems with the pix. they are really high res so they can take a bit
to d/l. if they are too small, just rightclick and d/l them so they can pop
up extremely huge. thanks again to everyone.
