The 813 is a very nice tube. However, if you can swing 7.5A of 5V, try the tantalum anode 4E27A. In the 5-125 form, it is comparable to the 813 in terms of plate dissipation, but is a true, 3-grid pentode. Very nice sounding too...:) IIRC it will do 35W with a 5k load on about 600V of B+( check the data sheet ). Stomps all over the driver sized tubes like the 45 and 2A3...:)
cheers,
