I'm servicing a somewhat obscure model (at least I've seen few of these in my 28+ years of amp servicing) 1600-B, bass amp (1x15 combo) that has a defective I.C. in the "differential" of the power amp, that I can't seem to find through any of my usual semiconductor suppliers. On the original schematic, the [16-pin] I.C. is an LM391N-100. If anyone knows where I could find one of these, or a suitable replacement, I would be grateful. I've all-ready tried, what was SUPPOSED to be an SK series sub/replacement, with no luck (I rarely have luck with SK's anyway. It was out of desperation that I even tried). Thanks...Mac
