Tube Rolling the Don Allen 807

Is it worthwhile tube rolling on Don's 807 amp?

I have Don's 6550 amp (I mean literally, this was Don's amp that he sold me as he was busy helping a friend in need) and in my experience, swapping the power cord made zero difference, and tube rolling the drivers made no difference - although some benefit was achieved by rolling the power tubes to the Tung Sol NOS 6550s.

Not sure a benefit can be found on rolling the NOS RCA 807, RCA 7C7 or the RCA cleartop 12AU7 (or the rectifier 6BY5 for that matter!), so I was hoping to leverage the experience & expertise of AA here.

Any recommendations based on experience or anecdotal events?

Thanks!!

Paul
