hello to all asm1 builders and developers just building the asm1 vco twice but only got one 2n4391 at home. it is a great module with outstanding stability, but the 2n4391 is obsolete. now i wanted to ask, as i have a couple of BF 245 c at home, if i can substitute them for the 2n4391. thanks chriss -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net
