Finally i found the time and try the russians 6n16b
i found there is a mark at bottom glass that shows the plates (8&5) so was easy to make the wiring ..i did not noticed that before .(not easy to see anyway )
..well it seems or i did something wrong or this tube make capitole sound like ipod !!
I must say i tried the tubes also to prima amp and prima cd -before use it to capitole- ..in all cases was dissapointing
At first you think the sound is interesting ..but soon is obvious it is just "nice sound" music is not there !!
compare to raytheon it is like a bad joke !!
The heater is quite more (100-140ma more than 6021)i dont know if this is a problem for the power supply.. but i dont think so..
Anyway i did the tube rolling and i use differnt systems ...to make a long story short ..the tube for sure is not made for audio!!!
No need to say i check power supply voltages etc ..all tubes was ok (capitole has 5,9-6v for filament lower than typical but thats ok ..or maybe is better?)
It is really mysterious ...so bad tube !
I really wonder.....if the extra current tubes need is too much for the player supply!! or something else that only russians knows !!
First think that the tubes 6021wa and 6111wa have an expected lifetime of
about 10000 hrswhen we started with these miniature tubes I proposed to use the 6111wa which has less gain and comes close to this russian 6n16b
replacing the 6021 by a 6111 is easy as they have exactly the same shape.
this might be a better proposition then that funny brother PUTIN-tube.
