New production Tung Sol 7581 in Mesa simul class?

I am wondering if the Tung Sol 7581 tube can be safely used with my Simul Class 295.

If they bias up right,they will be okay.I use NOS RCA 7581A's in my IIC+ with no problem.I had to set the bias,but otherwise they work well.If you can check the bias,give it a try.
