What are these?

They look like some type of amp. :scratch2:

Not mine, no affil.

For $35, nothing to lose there. I'd do it. No idea on make other than they say Made in Canada on them.

The model is Multi-Vox GBR201. Looks like it's meant to be used for a multi-speaker system in a store or an office building.

Does that say Garrard in the bottom corner? I think my money is also on some sort of intercom or multi-speaker system. For $20, it's gotta have value to diy/custom amp builders.

I'd guess the heat sinks alone are worth $20. There could be other good stuff inside too. However, if you're not a DIY'er, that stuff might not matter.

I'll pass, don't need the iron.

I think that brand is Girard, not Garrard. Yes some sort of industrial amplifier with 70 volt outs.

Public address audio amplifiers, with taps for 25 or 70.7 volt speakers. Not sure about the CT labeled terminals. Similar to a Dukane amplifier.
