Are there any qualitative differences in sound and build?
I'm trying to grasp the price differences in that link among the same type of tube.
I don't really have a budget, but I have a "wife filter".
She would have killed me if I bought that CMA800R the other day, but I think I can get away with a few tubes under $200.
I'm partial to Siemens and Amperex, that is in the $60-$70, but like I said, you can do 1/2 that if you wanted. The GE Smokey glass ones are also supposed to be great.
I would look at this tube right now if I was you:
It's a 1964 PQ Amperex (US Made)
You can do make an offer and I bet he would take $60-$65
**I have no affiliation at all with the sellers, I actually picked it myself to eye**
Another great one for about 1/2 the price is the GE Smoked ECC88:
I think I'm missing something there. I have 10 free pickups at the depot I mentioned, haven't used one yet. What's the PO box do?
btw, 24 = case of beer, the last few times customs waves me through (and with fees it's still a lot cheaper, you lucky Americans!)
Just as an update for my problem last night; I came to my pc this morning expecting frustration but it worked perfectly today without even changing anything!
Electronics are weird...
Sounds great through my Lepai and now I'm waiting on parts for a SennGrado build! Should sound fantastic!
Hey guys, add me to the club, my T1 arrived today. It came with the EH 6922 valve. Loving this thing, paired with DT880 Pro 250 Ohm. My AD700 also sound great through this little thing, so much so that I'm selling my Sound Blaster Z. I'm reading through the thread as I'm writing this, absorbing information. Here's a couple of pics I took earlier tonight
Hello all, newb here.
I'm just getting into quality audio and I've got some tube questions.
I did a lot of research before making any purchases and ended up going with AKG K550, Aune T1 DAC/amp, and I've just received my first tube to replace the stock 6922EH: a cryo treated Amperex 7308 vintage gold pin NOS tube. I assume it's a 'white' label tube, but I can't really tell. There's not much of the fragile ink left on the tube and it looks more grey than anything. FWIW, it's a JAN tube (so must be a US made tube, not Holland, correct?) dated 1966.
Anyway, the box the tube came in has the following:
T1=11000, T2=11000, noise=A, microphonics=A
What are the T values and is higher or lower better? Is 11000 any good? Same with the noise and microphonics, I assume A is good... what's the scale?
And lastly, do tubes burn in and settle into their sound after a few dozen hours on the Aune T1?
