Thanks Stef, 

I found 2 suppliers wdgreenhill.com and fibra-brandt.com that both
sold the LM326N IC, Just in case anyone else ever finds there DS-1
without any positive or negative 12 volt power.

I think wdgreenhill.com has the better deal basically about $29.73
total including shipping.

I know it's a lot to pay for a power supply IC that can actually be
replaced with more standard parts that nobody would ever see, but then
it also requires less custom work and actually lets the DS-1 remain in
a more stock condition. (not that it was in anything remotely close to
minty condition when I got it.) 

Thank for your help,
Cameron
