problem with some channels, and some tube advise

[c-chavez]

Hey everyone, I'm new here but have had my triaxis for over 1 year now. The problem is that when I use the LD2 channels, they sound very very very low, it doesn't matter if I turn all the volume up!, so I was wondering, would it be a problem of tubes? or should I send it to mesa boogie for them to fix it?

What happens if one tube doesn't work? will it affect the signal?

And talking about tubes... which ones should be the ones I should replace the old ones with, if I had to? any reference? I've heard the 12AX7 are great, but I was wondering, should I buy 5 of the same tubes? or 5 different tubes?

thankx to all, and mesa rocks!

Your V4 may be K.O.
If you liked the tone you had, juste replace it with the same tube.
Otherwise a NOS tube in V1 and V2, non-microphonic tube in V4, a low gain tube in V3 and a low gain and balanced one in V5 would be perfect IMO
