Amp issues

Hey all,
So I have an issue with my amp and I thought I'd consult with you guys before doing something about it.
I have an Orange Dual Terror (basically, a 2-channel Tiny Terror amp). During practice about 2 months ago, I lost gain on one of the channels. I was still getting sound from that channel, but I was only getting relatively clean sounds (despite driving the gain all the way up), and the tone I was getting sounded a bit off (a lot of the bass was gone, so it sounded really trebbly). I continued to use the amp on the other channel, thinking I'll deal with the defective channel later. Well, a few weeks later, the same thing happened to the functioning channel, so now both channels sound like shite.
I'm guessing this is a tube issue, as I've had this amp for approximately 7-8 years (and I bought it used). The tubes haven't been changed since I've bought it, and the history of the tubes that came with it is unknown. I was going to just go ahead and replace all the tubes, but I thought maybe I'd run it by you guys first before I drop $150 bucks on this issue.
What do you all think? Tube replacement? Should I get an amp tech to look at it?

But I do want to stress that you should take it to an amp tech - DO NOT fuck around within a tube amp unless you really know what you're doing.
New tubes would be my first suggestion too.

Sounds like maybe I'll purchase new tubes - I'm thinking I might as well replace all of them since it's been a while and they're all probably due soon (4 12AX7 preamp, and 4 EL84 power amp tubes). Based on previous threads here at DRG, sounds like people recommend the JJ ECC83s and the TAD-EL84-STR, so I'll go with those. From what I've read also, seems like I can do this myself. For the Dual Terror, there's no biasing required either - so it sounds straightforward.
Thanks for the input everybody! This is my first tube amp, so I thought I'd consult the experts here.
