On Mixing output tubes -- Is this a good idea?

I have just replaced a bias resistor and EL34 tube on my Anthem AMP-1. Since I am getting fed up with having blown bias resistors, but getting good at replacing them, I just find a spare tube and plug in in with a new bias resistor and then bias each tube to about 35 ma.

I noticed that the amplifier is sounding awfully good. I also am wondering if this is the result of mixing output tubes. I mean a GrooveTubes for good bass and a EH for a clear midrange, all on one output side. The other side has a EH for that good mid-range again and a Svetlana for silky highs.

Anything wrong with this? Is it maybe advantageous?

Also, I don't bias often, actually only when I install the new tubes. Is this a big mistake? I think biasing is a big headache with about fifteen little screws to undo, and then watchout for that high-voltage!
