Well, it was my first amplifier build, but I do a lot of electronics work, including SMD. I would think this amp is intermediate, you should be pretty decent with a soldering iron before attempting it.

I bought a lot of 20 12AU7/A variants awhile back, and I think every single one has a different label. I've got tubes from so many different companies... RCA, Sylvania, Amperex, Matsu****a, GE, etc. Do any of you know any good sites that have good clear pics and descriptions so I can identify exactly what I have?

There is this one site but I have forgotten the name at the moment, however if the tube does not have any label it will be hard to discern. There are so many tubes variations between each label, it will be hard to look at pictures to figure what they are. If they have labels brand and tube type you can do a search and they may come up. Buying lots is a good way to find some good tubes. I just got one set with with a raytheon black glass with d getter.

Thanks for the images! I can't believe i didn't notice them before

olblueyez, great recommendation with the E82CC Siemens. I just got one in a bunch of a dozen 12AU7/ECC82 tubes on eBay for a bargain, <AU$4 each =D

It just sounds right.

I am glad it worked out. Cryoset.com has some Triple Mica 5814A Siemens tubes branded Siemens E82CC for 50 bucks ea. I got a couple of those in addition to the regular E82CC and so I figure Im set for life.

Too bad I missed out on this deal, I even had it on my watched list, but I was away from ebay determined not to spend money for a little while. Somebody got a great deal though.

Those are not the best in the world but at 10 bucks a pop it would have been a great bargain for seller and buyer. I never have tried a 5 star GE. Hummmmmm.

Yes, they are very nice but I cannot say they sound that much better than the standard run of the mill E82CC so it is probably not worth 100 bucks I spent, HOWEVER, it is a ruggedized tube and will last forever and cryoset matches them for you so if you had a B-52 or some other amp that uses them in pairs then that would be IMO the best buy available unless you wanna try a 350 dollar set of Telefunken ECC802S. I could be totally wrong but it would seem that since both are from Germany maybe they came from the same factory, but I dont know, that is just a guess. Anyway, for you CTH guys, if your not lookin spend 50 per tube just stick with the E82CC, if there is a difference I cant hear it and im usually good at picking that stuff out.

just put in an old mullard ecc88...

very very promising so far!

great slam, huge bass and the mids are something else..... it appears to have dethroned my old fave the 8416

Mine has developed a wonderful bottom end with plenty of power and depth. Waiting on a Siemens tube to arrive which will hopefully be even better.
