A few basic tube questions

For starting info i just purchased a pair of Quicksilver mid mono amps . These are my first tube amps i have owned .

Questions are : I plan on buying several sets of tubes for these amps by different manufacturers. When i have found the ones that i feel i like the best how do i sell the others that will have had an hours worth of use ?

Second question is in regards to the varients my amp can use . They are el34 , kt88,kt90 , and maybe a few more .Will all manufacturers of an el34 sound similar . Or might one el34 sound like someone elses kt 90 .

Third question is in regards to my new dodd preamp . That uses one tube of the 6 volt ilk . There are one of those as well in the quicksilver amps . Is it a good idea to use the same in the pre and amp ?

Lastly if anyone is interested in giving a quick (general description) on the differences of the el34 ,kt88 ,kt90 tubes .

Another source of knowledge are reputable tube sellers. First, and to my mind, most knowledgeable, is Andy Bowman at Vintage Tube Services. Second, Brent Jesse, third, Upscale Audio.

Any one of these can provide you with information about which tube work in which components.

Of course, there are a number of forum members that can provide very valuable knowledge as well.

Good Luck, enjoy,

In my experience, I find a broader choice of high quality NOS (new old stock) from the likes of Vintage Tube Services, Brent Jesse, Upscale, etc.

I've found NOS tubes gerally sound better, and should last longer, but they are more expensive. Try a few, and see.

Best regards,
