yellow jackets in a mark III?

[JimAnsell]

can you safely use thd yellow jackets in the 2 outter sockets in class A mode?
while keeping 6l6's in the inner sockets?

I've used them on the outside sockets and ran it in Class A. They sounded fine. It lost head room and overall volume as expected. I play mostly in Simul, so they had to go. But they were in there for 2 months (played every day) or so and I never had any issues.
