Hi!

I have to confess I've always been lucky with ECL86s – all those I've come into contact with have been absolutely fine with no noticeable grid–emission or leakage!

I will add, however, that Mullard's "Low Consumption EL41" operating conditions, (Va = 250V, Vg2 = 210V, Rk = 220 Ω) , which is also applicable to lower–power use of the EL84 as well, does go a long way towards prolonging the life of these valves – the Marconi 4238 reel to reel I sold has it's ECL86 used under these conditions, and it's o/p valve was still in first class condition with plenty of volume and almost total absence of hum and noise!
