"Stevens converted this Bogen PA into a single-channel Marshall-style 18-watt combo with a single 12AX7 and two ECL86 tubes for about 13 watts of output. He built the enclosure to mimic the two-tone blue cosmetics of vintage '70s Univox ""Group B"" amplifiers. The cab houses a Celestion Classic Lead 80 and a Weber Mini-MASS attenuator. He says, ""With humbuckers, it sounds very Zep-ish, but I usually use it for my '80s new wave thang."" "
