What is the correct power tubes for the Sunn Sonaro? Mine has 6550`s but seems like I`ve read that they came with EL 34`S???

my buddy has one with 6550's.  his is (i think) a '68 head only.  I think most of them had EL-34's.  might have been a year thing, I'm not sure.  I don't think EL-34's fit in 6550 tube sockets so unless someone has replaced sockets, yours is one with 6550's(KT-88's)
