post #4576 of 6067

Guys I am trying to verify two things.

 

 

1) Is the RCA labeled tube actually a US made Amperex as it was sold?

 

2) Is the Siemens a CCa or not?

 

 

I have more pictures, but I think this shows it all, the only missing thing in the pictures is the number 2 etched on the bottom.

You E88CC is not a CCA...but damn close

What tells you it is not?  Also what about the RCA labeled supposed Amperex?

 

What you showed is just a sell ad for a select few CCa tubes, they ran for years.

CCa tubes (real) are so rare...and if you did find one then

1) 95% say CCa on them

2) You didn't pay under $150

 

The add is not old and its NOT CCA. It gives you an idea of premium E88CC's

 

Many EBAY sellers list as E88CC, CCA or 6DJ8,CCA or 6922,CCA,

 

They are the first letters not CCA's

 

Even the ones MARKED CCa's should be suspect.

 

These MIGHT be real

I have no clue on the RCA....sorry

Guys you might want to start posting those etched factory codes for better identification.

Siemens ,Telefunken ,Valavoa are most common CCa ,most CCa are German types of tubes and only few were made outside  of Germany

  Most of what is available is Siemens or Telefunken made, although there are a few very rare examples of Philips or Amperex Holland made out there. Since this was a tube made specifically for the German goverment and military, all that I have seen carry a German brand label, even those made in Holland. Even rarer are the Holland made Cca tubes with the pinched waist indented glass midsections, said to be the most sonically "3D" tube ever made, of any type. Finding these is akin to finding a 1795 gold piece in your attic! I don't believe there were any of these Cca tubes made in the USA 

here is example of CCa (they all will test very high and will outlast none CCa ),I payed $230-shipped from Germany for both (1965)

 

NOTE; Siemens are most common CCa tubes

Well, got the Grados.  I love them but did have an issue with them initially.  There was a significant 'buzzing' in the right ear piece.  Checked them on my regular audio equipment an there was no buzz.  What I did is change the output gain on the Aune to 16db and the problem went away.  Planning on turning my wife into a Grado widow this weekend.  Happy happy happy.

I can't locate any etched codes   :confused: 

 

 

I did find an additional symbol though, it's on the opposite of the metal shield inside the tube and looks similar to an alpha symbol.

NCS..you may just have one or the not designated ones that are the same..I know that side getter code means something...I myself just don't know enough about how to 100% identify..

My review was ...

~~GE Labeled SIEMENS 6AQ8 ECC85 GERMANY - cant make out date code 5.0 Stars *****/ This bad boy is amazing, Soundstage impresses you immediately as does the detail. This and my other GE labeled tube will knock your socks off. Would make anyone happy -this 6AQ8 which I think has a tad better soundstage (by a thumbnail) but also just a thumbnail less bass. . I listened to about 12 different type songs and could find no wrong EXCEPT some heavy metal tune by Nickelback and that may be the mastering, I need to check. But all other cuts, gorgeous. Vocals will make your head spin and take notice.

6AQ8 right? Who was the first person to try one in the Aune and reccomend it?

Shots fired!

All kidding aside, yes the GE one us a great sounding tube.

Space Queen -

 

I'm a bit confused about this:

 

 Foobar2K/WASAPI >Aune T1[Smoked Ge 6DJ8 Ecc88] >DV 336SE[Tung Sol 7236/Raytheon 6SN7GTB]> DT880-250//HE-400

 

I'm a noob.  Why would you go from the Aune to the DV?  I know there must be a reason but somehow I'm missing it...

 

Thanks.
