On the wasp clone filter schematic, (CGS49), in the upper left corner with
the CV inputs it looks like both the BC557 bases are connected together with the emitter from the BC547, is this the case ?
Its looks confusing on the schem cause there isn't a junction dot.
or is it just the last BC557 thats connected??

Could some one clarify this ?


EDIT:
Doh! forgot to add the picture

Yes, both bases are connected to one emitter, you also can see that on the pcb layout on his page ... http://www.cgs.synth.net/modules/cgs49_twf.html
