Bias on Manley Snappers

I just had my Manley amps repaired and I use 6CA7 tubes with 12ax7 instead of the stock configuration of EL34 with 12at7's

Now with the stock tubes EL34 is says bias should be .3MA. When I try and bias my amps after the repair 6 of the 8 get down to about .310 but 2 wont go lower than .416

Is that a problem? the manual says never go past .5 with the EL34s

What's your thoughts? should I bring these back to the person who worked on them or is the .416 Ok with the 6CA7's?

Thanks
Bob
