In Reply to: And even if it does result in 25% more power, how significant is that really. posted by Michael Samra on August 2, 2016 at 15:02:33:
I'm confused. You warn against "pumping 430v into an EL84", yet earlier both you and others agreed that plate dissipation is more important than plate voltage in determining how hard a tube is being run and, I would assume by extension, its expected lifespan. Both 7189 and 6BQ5 have dissipation ratings of 12 watts.
I don't doubt that 7189s "take abuse better", as Doug put it. My earlier response was: I don't doubt the 7189 responds better to "torture". Would you characterize running a tube rated for 12 watts plate dissipation at only 10 watts as "torture"?
I can see how the 7189 would be the clear choice if the dissipation is pushed to the 12 watt limit or over, but at more reasonable levels does it really matter?
Say both tubes are being operated at the same points - running at 430v on the plates but only 10 watts plate dissipation, is there any compelling reason to use a 7189?
