The only octal JJ's I have are the 6L6GC , with that single hole on the plate. Mine have stood up, but it's the only output tube I have where I hear thermal expansion/contraction on start up and shut down. They have approx one year of use @ 4hr/day. The amp doesn't drive them hard - it was built for 5881's and I give them the same bias.
If JJ made a 5881 I might try it, but the Tung-Sol 5881 reissue did exceptionally well here.
