0.04 * 600 = 24 watts (75 watt max for he 75tl)
With the 75tl you could consider doubling the plate voltage to 1200 volts. As it is, running a 75tl at 1/3 dissipation is way down in the curves. The tube will have less distortion if you can bring up its operating point and it will make more that the 6 to 8 watts this operating point will give you.
I know there is the whole "cheap 300b" operating point for the 75tl, but these tubes are getting more rare and a JJ 300b is cheaper than the Eimac now. I do understand the fun of using the Eimac tubes, having both a 304tl amp and a 35t amp in operation at the present (both in the +Kilovolt range).
