I had similar problems to get LF411's locally, when I built my Analogue
Shift Register. Bad thing was I *needed* a low-offset opamp, because
I had already designed the pcb, without room for offset trimmers.
I ended up putting OP-07's in.They work fine in my ASR, and they
*should* also work in the 2600. But of course I can't guarantee for this,
'cause I haven't actually put them into an ARP.
