Tube mixing


So what would happen (theoretically anyway) if in a "push pull" tube amp where each tube has its own bias pot, you stuck disparate tubes next to each other. I have 3 sets of power tubes...if I put 6550s and KT120s next to each other in each channel biased properly (or to the amp specs), or a KT88 next to a 6550 in 1-2-1-2 pairs...would this trigger cosmic calamity? Gear meltdown? Audio magazine subscription rejections? Would the tubes sit there and stare at each other in disgust? I'm not necessarily gonna try this, but it seems to be a way to get the advantages of different tubes ALL AT ONCE! Ha...and hmmmmmm....

Wolf!! Disparate tubes next to each other? Un-matched quads in a tube amp. Don't do it!. You will upset the cosmic tubeworld balance. I'm going to short circuit as well. (I don't think I will ever be as funny as you.)

Anyway I'm curious to know what membership has to say as well. In the other tube amp I have there are 2 6L6GB tubes and 2 6V6GT tubes used together. The amp is supposed to have a quad of 6L6 tubes. From what other tubeophiles told me the split set-up I have in that amp is ok. I just have less power/channel. I never got around to having a quad of 6L6 tubes put in because I had to pay a tech to re-bias and check out the amp.
