Tube handling/designations

I recently purchased a BAT VK-30.It came with 6922 Teslas installed as well as the original Sovteks.I would like to try some different tubes to see how they affect the sound.My first question is do you need to wear gloves so as not to get oil off your hands on the tubes like halide lights?My next question is are 6922's the only tube that will work or are there others?I ask this because in some ads for tubes I see a slash followed by EE????.Also,what does NOS mean and why are they supposed to be better?

Your best bet is to replace all the stock tubes in your Bat VK 30. Also the 6922 tesla,s are a upgrade over the Sovteks but I recommend that you consider amprex bugle boys as a start in your quest for a bigger improvement in presatation and soundstage. Here is some additional info regarding these 6 volt 9 pin twin triode tubes...6dj8=ecc88 6922=e88cc 7308=e188cc tube(6dj8) cv2492=6922 and 7dj8=pcc88(a 7 volt tube that I have used with great sucess in my pre in leu of 6dj8's). Feel free to e-mail me in regards to extra quads of tubes that I have avaible from collection of slightly rolled tubes
