I've had my DT50 for about 2 weeks and I'm using a HD500 to control it. I'm trying to use ch. A with the Vox preamp and then when I turn off the preamp the DT50 reverts to ch. B which is set up as class IV. The problem I'm having is that when switching the amp 'pops' at full volume even if I keep the tube classes the same. It's been doing this since day one so I'm not sure if this is normal operation since the power amp section is reconfiguring or if I need to go through the return process.

Is there any easier way to do dual amp clean/dirty switching? I love the sound of it when it settles down, but it is impossible to record with and cringe-worthy when playing live. Anyone else?

Thanks
