EL84M

[Karl5150]

"A military-spec version of the standard Sovtek EL84 - the Sovtek EL84M's extended voltage tolerance - improved plate dissipation - and rugged construction make it equivalent to the RCA 7189. Chosen by Matchless for their designs - the EL84M also features higher transconductance - more power - and longer life than the less expensive EL84"
Understanding that BH generally designs amps that don't push the limits of the tubes, other than subjective SQ claims, would there be benefits to running these in the Seductor?

Audible improvements are unlikely - power, distortion, and noise would not change. Since it has slightly higher ratings (voltage and dissipation) it might last a little longer.

Karl,
 The only advantage that I can see to using them, depending on your age, would be that you probably would not have to replace them until after your dead.
