A little more work required then.

I will run the DC test on the ECC82 as that gave the biggest error and report back.

Perhaps just an observation but Martin noticed earlier in thread that the anode and sceen voltages were down compared with the 163. I can see these drop around a couple persent more than the 163 voltages do when I change from no anode current to 50mA. So in total perhaps a 4 percent drop. ?
