I've been using one of these for a while now to check the bias of my tubes., works great. You do not want to leave it in the circuit very long but for setting/checking the bias is OK.

All tube amps fluctuate somewhat. No matter what the Bias control technique or device is. It's the nature of the beast....
TheRazMeister said:Fenders are NOT "kinda" fixed bias. You can buy tubes in the same tolerance range but the bias will change even if you set it manually. My friend checks his Hot Rod Deluxe every few weeks and it fluctuates.
