Running +/- 15V opamp at 3.3v
The XR082 has a datasheet that suggests that with a 30 V (-15 V to +15V) supply voltage, you reliably get a 24 V output peak-to-peak swing.

So, that's a whopping 6 V less than the supply voltage range. I doubt it will do anything useful at a supply voltage of 3.3 V.

The MC34002 (datasheet linked is probably even from a good specimen) is just as obsolete: it has exactly the same output swing for a +-15 V supply (but the datasheet at least mentions the load to not be stronger than 1 kΩ... puh, that's not a strong load).

So, my guess is neither of these Opamps will work with a supply like that. They most definitely were never designed for such.

Currently, arrow.com offers free shipping, and in my experience things reach their destination the next day. Since you probably want some passives to go with your opamps, this would be a great opportunity to restock a bit  with post-1980s silicon!
