Question about tubes

Hello AG folks hoping someone can help me out. I have a Magnum Dynalab MD 109t not the SE version. It takes 4 JJ 6922 Goldpins (what factory installs) . I want to order a new complement of tubes. Are all 4 exactly the same or is there a specific tube purpose I should be aware of such as power or signal etc. I am not versed on tubes. Factory wants $300 Tube Depot $96 bucks thus my question . Thank you in advance for any direction

I don’t know the purpose of each tube in your MD, but unless MD does some extra screening of its tubes, which you would have to ask them about, a low noise, matched set of JJs from Tube Depot should be OK.

Manufacturers often ask a lot more for their tubes. Jim McShane is a tube seller highly regarded for his knowledge of new production tubes and getting people the right tubes. I’m sure he’d be glad to talk to you.
