You could also just get another pair of EH 300Bs.  There are a lot of people on the internet who wouldn't believe that you got 10 years out of a set of output valves.

I have had pretty good luck with Aliexpress but it is a bit trickier than Amazon. Ali has longer delivery probably? but lower price. PS Vane has started selling their tubes on Amazon.
