Thanks! I've just ordered the right parts from there... shame my local place gave me the wrong stuff. I guess I should learn more about the parts so I know when it will fit or not, hey..

Hi, I've tried searching for an answer to my problem, but no luck..

I'm trying to build a Cupcake (etched the board myself) but the trimpot doesn't do anything.
There is a signal coming through, I'm getting a a noisy boost, (the level pot is working - even dialed down to unity volume, there is dirt in the sound).
The odd thing is that disconnecting the trimpot doesn't change anything, nor does taking the transistors out - the dirty boosted signal still flows. I even tried taking the 3. hole from the trimpot space and connecting directly to the 1, which should short the signal, right? (again no change).

I had to substitute parts (local german store never has the exact parts!), and just went with what the guy at the store suggested:

IC - N1436
Transistors: BS107 & BS170

Any ideas?
Thanks!
