Extension cab for PRRI?

[=JL=]

Hi all, can anyone tell me whether it's safe to run an 8 or 16 ohm extension cab while still using the on-board 8 ohm speaker in a Princeton reissue? I know what the manual says about it, I was just wondering if it's a safe/advisable mismatch. Thanks in advance.

Pretty sure that'd be safe, with either speaker. I've never had a problem running a 2:1 mismatch with a Fender amp!
