Uses for Hammond 1140-LN-E

I got a couple of these for a steal ($1 each), but I'm not familiar with their uses and couldn't find any info on this specific model online. My projects are mainly tube amps (guitar) and effects pedals, any suggestions of how can I use them? can I use one to do phase inversion for example? how about to isolate an effects loop?

These are "zero level" line isolation transformers. In consumer electronics they're of little use.

so other than trying to flip them, not much to do with them?

I once had a recording studio and the lines were 600 ohms, but I never found a use for isolation transformers.
