I have a nice 50W tube head that runs at 8 ohms, and I picked up an unloaded 2x12 cab for it not too long ago. It's been sitting around for a while, but I finally found two awesome G12H30s to slap in there. Only trouble is, one speaker's 16 ohm and one's 8 ohm! So, I was wondering...if I rigged an 8 ohm resistor in there with the 8 ohm speaker, would that solve the problem? Could it hurt the transformer? Could it hurt the speaker? Could it affect the output or tone of the amp? Might there be another solution besides looking for another speaker?
