I should hear back from the tech tomorrow. Unfortunately i have had no luck with my randall gear, i got the RT250 in september last year and i had it gradually lose volume in the middle of a gig to the point that there was no sound coming from it, i took it to a tech who found nothing wrong with it, i got it back and it worked fine for two or three gigs and then it did it again so i sent it back and purchased the head which worked fine for a couple of months before it developed this problem.... so yeah hopefully everything will turn out ok but my experience with randall reliability has not been good, i do gig 3-4 times per week each gig lasting 3-4 hours....still i have never had an amp that sounds as good on EVERY channel as these amps, in the past i have had to sacrifice clean sound for good overdrive or vice versa but not with this amp, i get the best of both worlds, so please don't think i am putting the amp down in anyway because i love it.... I just worry about the reliability based on my experience.
