It seems to be ok for about 30 mins of playing time then suddenly a loud noise comes on while playing. Something warming up and getting too hot maybe? I'm thinking of sending it back to boogie for an overhaul. What do you think? Is there a DIY somewhere on how to change the LDR's I'm pretty handy with the soldering iron.

The 99 has the bad batch of LDRs and lost the red channel at a gig last month and the 94 lost its reverb first, then the orange channel. My question is directed to 94tremoverb... Where is a good source for buying LDRs? Im going to replace all 50 in both amps! I cant live without my t-verbs and cant have em going down at gigs! Im using my "backup" Roadster now... Not a bad backup huh? Its an awesome amp but there's magic in those t-verbs! HELP!
I got mine from Mesa's UK distributor (since I'm there). If you're in the US or Canada, probably contact Mesa directly. They may not be the cheapest option but you know for certain you're getting the correct ones.nyeguy said:My question is directed to 94tremoverb... Where is a good source for buying LDRs?
Actually that's one of the reasons I like them - OK, you may have to restrict what you can do with them (down to one channel probably) but there is very little that can go wrong with one that would leave you without a workable amp. There isn't an LDR failure I can think of that would leave the amp inoperable on at least one channel; it has both tube and solid-state rectifiers (fully switched, unlike the 3-channel Rectifiers) so a failure of either can be got around by flipping the switch; four power tubes so you can run it on two if you have to; with one spare 12AX7 (or borrow the FX loop one if you don't need it) and a few fuses you can survive almost any failure without carrying a spare amp. About the only thing that would stop it totally dead would be a blown transformer (which I've never seen on any Mesa) or a failure in the low-voltage supply or bias supply, which is also very rare to unheard of in Mesas. It might take a few minutes but I'm confident enough that I could get it going again that I don't carry a spare amp. (Although I do still have a last-ditch pedal-into-the-PA backup.)mixtery said:These amps are awesome live but I won't gig without a second amp again.
