Orange Dual Terror Issue

[albatrossoshinski]

I bought a dual terror and ran a pc112. i then bought a second. so i used the 8 ohms outputs to each cab, but now it only works on 4 tube outputs. ive had the amp for about 3.5 months and play pretty often, so im not sure if its the tubes or not. 2 tube outputs sounds like garbage, really awful noises, cuts in and out, etc. 4 tubes however sound wonderful. any advice would be much appreciated blokes, cheers.

Bring it back to the store... It should be under warranty.
