OK I played around a bit with a VERY gone tube (Ms.Pac's very burnt one).
The guns measured out pretty good still. Only the green was a bit weaker then the others. The Muter offers rejuvenation in 3 "levels". Tried clean first (just to play around, this tube is already written-off because if the burn-in). Didn't have any effect. Next tried the second level. Now the gun measured out MUCH worse than it was (I did like the micro-fireworks in the neck though
) . With the 3rd (highest) level I managed to get it back in the "good" range again, but the lesson learned (what I already knew): don't rejuvenate when not ABSOLUTELY necessary !
There's some calculations and graphs going on to fully measure the guns. I will create an excel sheet that will do the work (like creating the graphs for all 3 guns).
Wanted to test-drive another tube but had no luck. The tube is a A 51-211 X. The Muter table (thanks Speleo !) says I should use adapter 813. I've got it BUT the neck connector is of a different type. (For Speleo: it looks like the 803 connector).
I think I should be able to remove the connector to work straight on the pins, but still I found this a bit weird...
Stupid Hantarex
Anyway, went through the entire manual and it's not hard to do, but you do have to know WHAT to do.
I'm happy that I already have the right adapter for the Amplifone tube (808). Not that I would even consider playing around with that one, but IF it will go bad in xx years......
