Tube roll modded my 1987 Red Stripe 60w non-simul and stuck it through the same conditions as the Mark IV test.
Flying V, Recto Cab....no effects of boosts in this. (same range of cam and conditions)

V1 - Mesa SPAX7
V2 - Tungsol 12AX7 silver
V3 - Mesa 12AT7 (Channel 3 lead circuit)
V4 - Mesa 12AX7
V5 - Mesa12AT7 (Phase Inverter)

Enjoy..
