That OPT sounds almost as good with 6550s as the 7027s. I used to use a pair of Ampeg VT-40s for a stereo guitar rig, when the 7027's got scarce I converted both of them to 6550s. They still sounded great. You can also convert to 6CA7(El34)s but that OPT will not sound as good as the equivalent Marchall iron on EL34s.

You can use that transformer for a pair of 6L6's too. Skip
