Seeking more tube info. I'm new to this tube world.

Would there be much difference between these Amperex 6922 white label PQs? I believe that are both USA made.

1) 1960s halo getter; and,
2) late 50's/early 60's d getter

Thanks

Both are very good, but between the two I would likely go with 50s/60s "D" getter option provided the cost, condition, matching etc. are the same.

I ended up with the o getters as they were cheaper ($300 v 230 per pair). I was informed that the d getters were made til early 60s (I think 1861) then the o getters were used

I tried the siemens cca 1960s.  They are really wonderful in the wa2.  Incredible depth and texture and treble extension with gec 6sa7.  Tung sol 7236 provide nice power and speed: if you want to make your wa2 sound closer to a wa22- it gives that kind of presentation.

Have you ever tried the `74 or `75 (SWGP) 6N23P Reflektor?  Best extension (top-to-bottom) and smooth detailed sound I have yet to come across in the WA2.

I just bought a pair of Siemens Cca tubes (halo better) with the code of A1 6B. Does this mean they were made in Munich in 1966?

I've googled around and this is the only real, though not definite, conclusion I've made

A1 I think means 1st revision - they go up to A6?  In any case, the earliest I think are considered the best- so you've sourced some of the best siemen cca's.  Let us know what you think.

Will do. But this is all new to me. I've been quite itchy waiting for my wa2 to arrive.

Somehow I've managed not to upgrade a dac yet but I've picked up some used Gec 6as7gs, nod 6922 Amperex PQs (USA made), rft ez80 and now these used Cca tubes.

I'm ready to roll: Lots of homework to do in the upcoming few weeks.

The info on here, and the help of dubstep girl and others eg badas) has been great. And joes tube lore.

Yup, definetly 1960's tubes. Hopefully you'll get a pair without any noise. I have those exact tubes you bought but the e88CC version of them. The CCA I have are the later 1970's non a-Frame ones. They suck.

so these should be quite decent and quite special, if without noise?
 
do yours suck purely due to noise?

Yes. My e88CC are incredible. Ive been meaning to pick up some CCA like yours but im saving for some telefunken 308S tubes. The GEC tubes you have are great sounding but i highly reccommend getting some Western Electric 421A.

Here is my WA2

i've held back on the western electric/tung sol 5998 for now.
 
with my prefs, i've been told the gecs should do best with the hd800/wa2
 
i'll sus those out (and the stock tubes as a comparison) and go from there if i decide to look elsewhere
 
 
what are the telefunken 308s tubes - i haven't come across those
