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
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 usedBoth 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 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.
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.
Post a picture of the tubes you are asking about. You can tell what year by what the look like also.
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.
