Hi,

I've been trying to compare the data sheets between the MN4047B chips that I have and the CD4047BCN chips specified in the build docs.  What I'd like to confirm is that the MN4047B's that I have here will work in place of the CD4047. 

I think they will, based upon my beginners interpretation of the data sheets, but I would feel better if I could get a second opinion.

Thanks!

Sweet looking build!  I hope mine turns out as nice.

I spent about two hours tonight dredging through every thread I could find with a reference to the PTAP/PTAP2  on DIY.  I didn't think about BYOC.  Thanks for the tip!

+1  Stunning build!  I really like the switch breakout PCB.

I was going to pick up an Echobase board from MusicPCB and use it with that. 

I found the schem and such for the PTAP, but not the PTAP2.  I bought the PTAP2 so I could get the flashing tap rate LED, but now since the guy pretty much disappeared I don't know what I'm going to do with it if I can't find at least the schem for this version.  The soldermask just has component numbers, no values.

Thanks,

Andy

Hi everybody,

I recently found the PTAP2 PCB/ICs that I bought way back when, but I cannot for the life of me find the schem/layout docs.  Does anyone out there happen to have these?  I would appreciate it alot if someone did and sent me a copy.  All of my searching has turned up nothing.

Thanks!

Andy
