Tung Sol 6550 vs. GEC/Genelex/Gold Monarch KT88


Anyone have experience rolling these tubes, and would you comment on their sonic characteristics? I'd be using them in a VAC Phi 110 push/pull amplifier with Sylvania 6SN7 WGTA driver tubes.

I assume you have read the Vacuum Tube Valley shoot out - in a recent issue.

Regards,
'Vacuum Tube Valley' is such a good resource for tube-related info that I'm surprised more people don't read it. http://www.vacuumtube.com/

Issue #19 contains LOTS of info on 6550s/KT88s/KT90s. With new tubes costing $40 - $80/pr. and NOS tubes going for far more, #19's $22 purchase price is well worth it IMO.

Metralla, no I haven't read that article, although I'd like to, and I'll order the back issue tomorrow. In the meantime, any highlights would be appreciated, especially as related to Tung Sol 6550 and Genelex KT88.
