[sdiy] New supplier for MN3xxx Panasonic parts

Well Shanghai Belling is making MN3207, MN3208A (8-pin DIP), MN3208B (14-pin 
DIP like the original), & MN3102's. Their part number replaces the MN with 
BK: BL3207, etc.

You can buy them from Small Bear Electronics:

They're right up top. And the prices ain't bad! I've been waiting for 
quality feedback from people who've used them, but I haven't seen anything 
really. But I wouldn't pay outrageous prices for brand-new analog delays 
when you can rool your own for dirt cheap: you can get 8 or 9 BL3208's for 
the price of an MN3005.

I've been planning on replacing the MN3207 in my little Realistic Electronic 
Reverb - which is wacky stock, even more wacky and toneful with the mods I 
gave it and should be a scream with twice the stages! I thought of making a 
little board and putting 2-4 in series. I think they'll fit...

I really wish they'd gone for the PMOS parts - especially the MN3005 (even 
though I already have TWO modulatable delays that use them), but I'd imagine 
the NMOS versions wre more viable using modern tooling.


cheers,
aa
