"Secret 6505/5150 Combo Tip from Peavey
Want to reduce the wattage of your 6505 or 5150 combo? Simply unplug the speaker and plug it into the extension cabinet jack. This will cut the the wattage in half as the extension cabinet output only runs at 30 watts. "

I've never heard of doing this before. Doesn't this kill your amp?
I've seen that before.

Not sure if that's really true though, because with a cab plugged into my old 5150 combo, it sounded just as loud through the combo speakers as it did through the cab

I do that with my Vetta and it's a VERY noticeable difference in loudness between the combo speakers and cab (running at 16 ohms, half wattage).

I've had tube amps for a while now, but never actually had any go down on me

maybe you're not saying the right things? an amp likes to know you care.
