...It seems odd that disconnecting the sig gen should cause such a catostrophic failure. I've unplugged/turned off the sig gen gen loads of times before, without issue. However I was using a different sig gen yesterday.

Interesting... how did you connect the signal from the SG to your amplifier?
Were the grounds of your SG and amplifier also intentionally connected? Just trying to establish what might have happened as you imply a strong cause-and-effect relationship between unplugging the SG and the fault arising.
