WTB: Operational Amplifiers (Teledyne, Union Carbide, Valley People) etc.
 

I am looking to buy any vintage, bakelite cased operational amplifiers
from the above manufacturers and others such as Philbrick, TI, etc. I
am especially looking for any in case colors other than black as well,
black being the most common. Cases are approximately 1"x1"x1/2" with
6-7 leads off the bottom.
