My last two were from EBay, I don’t recall were the two Sylvania tubes were sourced.

I got two sylvanias on eBay, but the rest of my tubes came from Brent Jesse at audiotubes.com...eBay seems like a crap shoot.

Ebay - only sellers that offer returns, and have 100% feed back. Also good, if they mention listening for noise and microphonics with headphones. Also I try to only purchase tubes on ebay, if they list test results. Following these guidelines, has brought me good success, purchasing tubes on Ebay. Lastly, I love when they have good pics of the pins, and then a photo looking down at the top of the tube, to look for burn marks (used 6SN7 tube), if it has bottom getter.

Great advice. Ebay is still a crap shoot regardless, but the risk is greatly reduced with some careful scrutiny like Wes suggests. I've bought a lot of tubes on Ebay over the years with mostly good results, but have been hosed a time or two as well. Helps to have a tube tester too. :slight_smile:

A few to add to the list:

Vintagetubeservices.com (Andy has been at this for a long time, and is honest and very knowledgeable)
PartsConnexion.com (rarely have the uber desirable NOS tubes, but have fair prices on what they do have)
vacuumtubes.com (SND) (good selection, market prices, stand behind what they sell)
tubeaudiostore.com (Ram Labs, Roger Modjeski -- expensive, but you get the genuine article that's been thoroughly tested)

So far between the stock tunsol, mouse ear Tung Sol ,Sylvania bad boy and 50s rca the rca is my favorite tube. Granted, none of the tubes even have an hour of break in on them and the amps probably got about an hour on it...I just love the warmth of the rca. I have 2 other sylvania chrome domes to try and an rca grey glass, and sylvania 6sn7wgt that should be here this week at some point to try out. Probably going to stick with the rca for a little while to actually let the tube/amp break in a bit. All tubes sound great though, this is deff an amp you can stick just about anything in and enjoy. Also kinda impressive a 30$ rca tube out performs a 90$ bad boy atleast to my ears.

I'm not too surprised. The bad boy, and other very expensive tubes like the KenRad Black Glass / Melz / RCA grey glass / etc. seem to have earned their reputation in OTL and output transformer coupled amps. The Lyr 3 is an altogether different thing.

For example, I think the KRBG sounds great in the IHA-1, but it rolls the treble off way too much on the L3 for some reason. The new production TS 6sn7 you can get from Schiit sounds very good in the L3, but sounds etched and grainy, with a certain hollowness on the IHA-1.

This is fine. If I'm doing to drop $$$ in tubes so I can experiment, I'd rather get 1 great tube, and 3 or 4 good tubes out of it -vs- 1 average sounding bad boy.

That is interesting with your KenRad. I am getting too much top end, on a bunch of songs, with all 4 of mine. . .different strokes for different folks. I say if you have the funds it is worth trying them all out. The fact you only need 1 tube really cuts down on cost. You can find used tubes, of all brands and give them a try. Once you find the ones you like, then look for the premium NOS, and stock up.

I would like to add, that I listen to a lot of electronic music. Not any dance music, the chill stuff, like Max Cooper and Christian Loffler. I also listen to a lot of James Blake.

The 4 Ken-Rad, tubes I own.
My KenRad bottom getter tube is a little too bright for me. I don't have my two KR tubes here or I would take pics.

Mine all have staggered plates. I have 1 black glass, and the rest are clear. All with bottom getters. I do not hear a difference between the clear glass and black glass, with both having staggered plates (diagonal to the long edge of top mica, looking down from top) and bottom getters.
