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.
