If it still works properly, then I reckon it's worth hanging onto, all you'd need is a speaker cab with the correct impedance and enough power handling, hope it all works out.
I'm definitely hanging onto my Fender Super Twin amp, I've got a great amp with EL34 tubes in it, and now I've also got a potentially great amp with 6L6 tubes in it.
I'm just wondering if those Sound City amps are based on the Marshall JTM45, which was based on the Fender Tweed Bassman, from looking at the front panel layout, it looks similar to a JTM45.
