Read again, Romy. No burned sockets, and none reported; just dirty pins and then failed 5156s, as reported.
While I do have two busy and curious granddaughters one might at first suspect, I now believe that I cracked both 5651s MYSELF when I "rocked" them gently in their sockets (with the amps off) as part of the pin/socket cleaning ritual. This theory would account for both tubes having cracked bases and both failing at once - from the cracks. And since there is no vacuum in this case, "white out" was the result when regulating gas escaped out cracks. Many tube amps; many tube cleanings; first cracked-by-me tube bases. Live and learn...
Again, I did noit notice (or hear, for that matter) any other damage, so that seems to concur with your sniffing at 650mA as no problem for the 6N6Ps.
Best regards,
