6922 / 6DJ8 / 7308 / PCC88 for your cj pre amps
I think it is time for the 6922 thread and how they sound in your cj pre amp or amp vs the stk EH 6922 tubes from cj.
I am sure we will all learn from what each of us are using and useful to have everything in one thread. |

I am using stk EH cj 6922's and I have tried JJ 6922's. The EH 6922 is very good imo and is quiet and neutral.
The JJ 6922's I have are a little rounder in the bass, relaxed in the treble and just a bit warmer all round. I prefer the EH 6922's in my system. I just ordered from upscale audio 3 x Telefunken PCC88/7DJ8 - This is a 7 volt version of the super-expensive, impossible to find 6DJ8 3 x Philips Holland / Pope PCC88/7DJ8 - This is the same thing as an Amperex Bugle Boy. Why did I order PCC88's. They are fully compatible with 6922 tubes and have a longer life. Telefunken and Amperex 6922's are a LOT more expensive. Also my TW Acustik phono stage uses PCC88's, so opportunity to tube roll with two components. I'll update how they sound after I receive them. Last edited by turntable; 01-06-2012 at 10:52 PM. |

But remember to undo the mod before frying your ECC88/6DJ8 in the modified preamplifier. |

No one has mentioned this before. Upscale audio and others actively say they are interchangeable. There are clear sound differences between the telefunken and pope pcc-88's between each other and the stk EH 6922's What tubes characteristics are suffering? |

I'm using Ediswan CV2492s in my LP70S amp; they have a beautiful, textured midrange quality over the stock EH6922s while remaining extended at the frequency extremes. "Pungent" is the word that the guy from Upscale described for them. Also supposed to be very nice for the Premier 16/17 preamps.

I try to avoid NOS tubes because of the hit and miss nature of using them. Out of the current production tubes I like the Gold Lion 6922 best. Detailed, slightly warm and extended at the extremes.
In power amps the input voltage gain tube will have the most effect on the sound. |
