Air Tight ATM-300 bias setting - He

81.200.225.99

Hello all,
ATM-300 owners, please, do you know if is there inside the amp a potentiometer for balancing the bias of the 300B valves?
Originally, the tubes were EH 300B with 48mA and 61mA written on the boxes and the bias is same reading on both channels.
Now, I've tried a brand new matched pair EH GOLD grid both tubes 47mA and the bias reading is different, thus the right channel is louder than the left channel.
Please help me to set the bias because for sure other owners of the ATM-300 replaced the tubes and should know how to tune the bias.
Thank you in advance.
Best regards,
Alex
