Hi, Sorry was just being stupid, sorted it out after posting question. That's all my parts ordered. To anyone trying to buy BC557C's their is a guy in China selling some but costing me £113 to get 32 of them shipped to scotland.

I got hold of two industrial 24V supplies and derive -24V, -15V, -12V, +5V, +9V, +12V, +15V and +24V from it. Even have several modulars running on the same supply. > Dirk > > Kris Bishop <bishopkris40@h...> wrote: > > Hi, > > I'm currently pulling in all the components I needed for my Formant > MSS2000 to be built.
