That's a tough one.... the 6528 is on par with the 6336 dual triode (30 watts dissipation per section) but is overkill for a couple watts. It does have a mu of 9 which is quite high for a large IHT dual triode. It should easily drive a 1K load, but still too low on gain.

One possible option is an 8417 strapped in triode mode. Some modeling shows:

Plate supply = 250V
Plate Load = 1250 ohms
Grid bias = -7.5 volts
Cathode current = 125ma
Plate dissipation = 32 watts
Power output = 2.5 watts

Not quite what you're looking for but close.
