i have a v2 archetype and it works great but its in a warehouse that gets pretty cold during the week like 45 of so. Then when i turn it on and let it warm up for awhile its ok then i take it off standby and i have like half power for like 3 to 4 min then it kicks on and sounds great it started this when it got cold does that sound normal to anyone else cuz my jcm900 warms up and plays fime in the same amount of time ,,,i was wondering if this is normal cuz of the solid state power amp ive only had tube amps until this one any help would be great thanks
