It is one of Guy's just e-mail him for an opinion I'd say. Also, Tom had one (Montesqieu or however you spell it) that he had up for sale here and claimed it was fully Amperex'd. Could e-mail him.
You could just plug the f*cker in and see what happens. I'm awaiting the mushroom cloud in Portishead...
The OTK stamp means mil spec 6N6P so it appears. There's some gold grid non-OTK ones around and a Chinese knock off too that I haven't seen before. Actually I was aware of the non-OTK gold grid ones now I think about it. 10 gold grids for £30 odd quid isn't bad really. My OTK ones have been going for years now with no issues.
Which Rusky one(s) have you actually got?

The L10 only has 2 valves inside.
The 6n6p and a 6z4.
I can't recall what 6n6p is in there, but I'm sure it didn't have a red nip - and I can't be bothered to take it out of the rack and pop the lid again!
Yes, I noticed the gold grids on eBay, some gold pins as well.
I've ordered us a batch of 8 gold grids for £20 from sunny Ukraine?
I'll keep 2, you can have 6.

Pin 9 is an internal shield in 6n6p, in ECC99 it is the heater centre tap for 12.6v operation. Check with Guy, will depend on the circuit.
“Music has always been a matter of energy to me, a question of fuel. Sentimental people call it inspiration, but what they really mean is fuel. I have always needed fuel. I am a serious consumer. On some nights I still believe that a car with the gas needle on empty can run about fifty more miles if you have the right music very loud on the radio”

My SJS pre has been modified (much to Simon's dismay I suspect given some of the components) to use a 6N6P so I did a little research on the tube and what could be had/found. The red top it is suggested is a "specially selected" marker and probably 1970s vintage.
The common consensus appeared to be that the best sounding ones were 1960s OTK (military quality approved marker) versions. I have 1 spare 1965 NOS OTK tube if you fancied trying borrowing it to compare. (PM with address Jerry). They are a PITA to find though now.

Thanks JP.
I'll PM you.
