I can't find much on google for an old Motorola chip, MC 34151P. It's an 8 pin driver chip. I'd take a suitable sub, I'd like 20-30 of them. Can someone assist? I know a few of you are in the parts business...

http://www.datasheetcatalog.org/datasheet/motorola/MC34151D.pdf is the datasheet
I found some notes that ON Semi has the same part under the same number...
These guys claim to have inventory: http://www.vctechnologyinc.com/search.aspx

THanks, turns out it's not that rare. I thought it was an MC3415, not a 34151. THe last '1' was rubbed out on the chip that I have here. Digikey has them, 20 are on the way to me.
Than ks!

Mike I am sooo far from even starting, I need to put a set of HD 144's on my Second Projector, then i need to do the belly fan mod to it(its still on the ceiling) . Onece that is done i have to get both set up on the floor to find the right
placement for their move to the ceiling. I still have the 12 foot 16x9 and am contemplating going to a 14 foot 2.35 to keep my 16x9 material close to the same size I am use to now. So if i do a blend on my 16x9 it will be temporarily till i decide on my final config, I might just keep it at 12 feet and blck out the top and bottom leaving a section to drop down for subtitle movies when the situation calls for it. And I was thinking of bring the units to Cliffs meet if he has time maybe to try them out, since hes allready converged it be a snapp to slap them in and see what they can do. I am not familiar with the controls but it shouldnt be that hard.
