I know after saying don't buy expensive tubes that may sound weird, but I have a Siemens E188CC coming in soon to pair with the one I recently found, I'll update you on that. If I think they're not worth the price I may sell them on the thread here first.

Actually no need to spend hundreds of $ on expensive tubes, first try some RCA or GE 6BQ7A I think they're great and you'll pay between $5 and $20 a pair. You can also have some HP-labelled Amperex for around $50 a pair which are great.

Well... I finally pulled the trigger and bought a second Siemens E188CC from tube museum to pair with the first one I found (RCA labelled) this tube rolling is an expensive disease!! Hopefully they'll sound incredible!!

Thanks!

I was wondering because I had never seen a getter like this

yeah, ebay   http://www.ebay.ca/itm/TRANS-RADIO-6DJ8-6922-E88CC-7308-ECC88-tube-4-pieces-BRAND-NEW-/121157343410?pt=Vintage_Electronics_R2&hash=item1c358a58b2&_uhb=1

Did Zenith produce their own tubes or were they sourced by another company?

Thanks for the info! I saw a double NOS pair (4 tubes) for $135 and was wondering, but that's a bit high IMHO

Does anybody know something about Trans Radio tubes?

Has anyone tested some Bugle Boy ECC189 and could tell me how they sound?

I'm really bad to describe what I ear, but at least I can say that RCA 6BQ7A black plates are really worth it if you don't want to rob a bank to have great sound! I'll have to let them burn in a little but first impression is very good!

Just got a batch of 5 NOS 6BQ7A today and was lucky enough to get 2 RCA black plates (with 2 sylvania grey plates hungary). I know these were mentioned as good sounding for the price they usually go for. Letting them warm up right now, but no noticeable hum or noise, can't wait! Also, if ever...

Man I wish there was 2 tubes in that auction! (even at twice the price) I don't know if these are THE ones, but I sure would like to try a pair of Lorenz!

It's been a while and I tested many of the tubes I found (at least the ones I had a pair of) and among my favorites are the HP 6DJ8/ECC88 made in holland which are dead quiet and sound very nice! plus they can be found for around $60 (matched pair)

Testing the Russians ('74 OTK) 6N23P cryo treated right now and i'm not really good at this but I would say the soundstage is great however the highs are a bit too damped for my taste. On the other side though, the amp is brand new, as are the NOS tubes, so I'll have to keep listening. Also, I...
