As the guitar player in Linoleum Blownaparte I use a pair of late 60's Sunn heads, a Sceptre and a Sentura I. The Sceptre has a pair of KT-88s that give it alot of headroom. It goes into a 2 X 12 cab and in a Motion Sound rotating speaker cabinet. The Sentura I has a pair of EL-34s which are running flat out through a THD hotplate into a second 2 X 12 cab. I use an ABY box to select the amp and a volume pedal to bring the Sentura up when both channels are selected. This gives me a lot of shades and, for me, the sound of the Sentura running between 8 and 10 is sublime.
