Stupid questions coming up. Does this mean that it is a must for the 12AT7 and 12AX7 tubes to be matched (each triode of the preamp tube has matching gain) and balanced (when the plate current draw of each triode is the same)for the Jolida 502P? I found that some tube sellers add a surcharge for this service.

Hi Marakanetz and Batch68
From seeing the tubes that came with the Jolida 502P I see I don't have to have matching 12AT7 and 12AX7 tube brands. It came with EH 12AT7 tubes and Tung Sol 12AX7 tubes. I normally like having uniformity all around but hey if it is ok for Jolida it should be ok for me.
I was wondering about the necessity of matching the gain of each triode of the preamp tube as well as the plate current draw of each triode being the same.
Here are some examples. Please see the Options check boxes
If matching isn't necessary I was just going to go to the music shops by me and get the Groove Tubes equivalent of these tubes. They aren't matched at all from what the associates tell me.
Thanks again for the help.
