wanted to know if this layout has been verified

I am having trouble with it

yes, its verified.

the "debugging" thread should help give you some clues as to whats wrong.

sorry for the hasty post ....
it was me
driled the wrong strip 

by the way why does the layout have a 100k volume pot and your other one has a 500k ??

I didn't have a 100k
I tried a 500k and am currently using a 250k
should I seek out a 100K ??

thanks dragonfly

500k allows a bit more bass, but is really unneccessary..the 100 is plenty loud and keeps the sound "well balanced". either one is just fine....

thank you for that info
I guess I can leave the 250k in there as sort of a happy medium

by the way couldn't find the specified transistors at the local Radio Shack
I picked up some 2N3906 which I will see how they sound tonight

right now I have some BC109 transistors in the circuit  but they measure around 300 hfe
I think that is quite high for this purpose
any thoughts ??

2N3906 is a PNP tranny...wont work...2N3904's sound nice though...try any NPN transistor and see how you like the sound !

2N3904 that's what I meant to type

thanks
