sanyo ld-3141
 

does the OPA 2134 replace the Sanyo LD 3141, and does anybody have a
schematic for both?

Thanks.

The LD3141 is an ancient, crude & simple opamp chip in a very bizare single inline package
w/staggered leads. There is no current equivalent, but you might be able to shoehorn in (i.e.,
pin rearrangement) something like an LM741 or LM301. You don't want to try to use something
fast, like an OPA134. I have no clue where to find pin config. data on the LD3141, except
perhaps in an early '70's Akai reel to reel service manual. I think the GX-270D might have
used that chip, but I am not sure at all, but old Akai reel decks are the only place I've ever
seen LD3141's at all.

Actually, I just found available LD3141 chips at dalbani.co.uk for about 4 bucks each.
