While my tuner was right here I had a quick look at it and IC3 is not an LM258, its a KA258.

They are both dual op-amps, are they both compatible/interchangable?


Yeah should be compatible enough. Nat Semi (the LM258) initiated a lot of designs that were later copied functionality wise by others using the same numbers but a different prefix to prevent any trademark issues I assume. Happens a lot with common parts.

Whilst a quick glance shows they are not exactly equal, I think you should be OK. Patrick might know more though and may specifically say the Nat Semi LM258 is the one to use.

Edit: your photo reminds me of when I was hacking up some code to drive my Alpine CD changer. I was editing on my Windows laptop to the local disk shared via wireless back to my desktop running a VM with Linux doing to the compiling putting the object back on that file share for download to the empeg... smile
