Oh no I hope I did not ruin my Mark V with new tubes

There were quite a few discussions on the wisdom of mixing tube types but if you stick to the same type you'll see on page 62 of the manual, the explanation for the Xs and Ys. The 2 Xs are active for 45Watts while the Y would be off at that power setting. It means that you only need to have 2 pairs of matched tubes and not a matched quad. Although when you order 4 power tubes from seller they should assume a matched quad. I know that the http://www.tubestore.com is what they assume when you order 2 matched pairs.

Now you say that you have 2 different looking pairs! I saw that the pictures show slightly differents bias current and transductence but I would put the similar one paires in X spot and the other similar in the Y spots. Does that make sense?

We could safely assume the physical twins have the same bias current.

I would say it is fairly safe to proceed since they are very close. I am no tube expert so you may want to wait for more knowledgeable people to confirm it or ask where you bought the tube.

thats what i was pretty much saying or trying to anyway

Make sense guys. Thanks for explanation. I gotta rent a cottage or tiny house or something. i was having a blast jamming when as I thought the people below me we not home so I was on 90 watts, on the great gramma, not overly loud but pretty loud and I guess they came home and were banging on my door all pissed. Glad it sounds good at low volumes and wattage.

Hello Sean,

I visited your Centrifuse MySpace page and liked the songs very much. I am curious about what settings are you using on your Mark V - I understand the tracks were recorded with your Diezel.

Best regards,
Marcelo

Hey thanks man. When i get a chance I'll take some pix of the settings on the Mark V. Yeah the songs on the myspace were recorded with a modded VH4 mono Head. Low bass as when i mixed it all I really did not like her bass lines....LOL hence we let her go back in December.
