Not sure that's a fair comment. To begin with, many people think the EH tubes are fine performers. c-j must have many tubes available for new equipment and for replacement stock and so must choose a brand that makes acceptable product that can be restocked. Certainly not any NOS. They then buy many hundreds of them before testing and rejecting a significant percentage, (a reason to buy your replacements from them). Their equipment at all levels is actually designed around this available tube stock. BTW, they would respectfully disagree with there being many benefits at all in tube rolling. On the other hand... love the sound of my Teles in Mr. GAT.

What tube, noting that it has to be available new and in quantities such that owners will have it easily available for many, many years down the road, do you suggest cj use? And I've had no trouble with the 6922s in my GAT since I owned it (now going on three or four years now?).

I've had three GATs in my sock draw and my sisters kids found some under the house. Oh, hang on, those were gnats.
It's the beta issue of low volume gear me thinks. The customer becomes the beta testing person. I had a couple of fuses go with my CA200 but then it settled down. My CT5 needed a grounding plate but now also seems fine and the LP70s has been good, touch wood. All was done promptly and under warranty and with a loaner when required or requested. We get good backup here in Brisbane, Australia. Last edited by Briz Vegaas; 07-05-2013 at 04:15 AM. |

Interesting that you mention fuses and the CA200. I've gone through more than a couple both stock and after market fuses on the mains connection. It would happen when I'd change power cords. When powering the unit back on, from the power conditioner, the fuse would often blow. I've since changed it to a HiFi-Tuning Gold XT fuse and, fingers crossed, it hasn't happened since. The XT is an extra slow blow type made specifically for units with a powerful transformer (such as an amp). It's exactly the value specified -- I learned that lesson with the 140. |

GAT Tube Noise
I was tired of listening to background tube noise on my 45 day old GAT so I popped in a pair of Genelex Russian 6922's WOW, WOW, dead quiet hope it lasts!
The thing that rubs me the wrong way with CJ and others is the fact that this is a $20,000.00 pre-amp and you use a $5.00 tube, why not pony up a few more bucks and give the customer a better tube? Their statement piece and their lowest priced pre-amp ET-3 $2500.00 use the same tube! I have a ET-3SE also and have had noise problems with it! On Monday I going to send my 3 noisy tubes back to CJ. Dead Quiet For Now. |

Supposedly they choose the best sounding tubes for which they can have confidence in continuing supply. They supposedly are picky about quality control within a given lot of tubes. I don't know how true either of these are.
I like the Genelex 6922's also. I tried several brands and have settled on these for my 17LS (not withstanding the possible tube failure problem I'm having with it - still not sure it's a tube). |

could never make tubes in the US on a cost effective basis. It's a wonder any of them work well at all. Obviously, NOS tubes are not options.

I'm not sure about the currently used tubes but back a couple years, cj's tube reject rate was 30-40 pct. You know what happened to the rejects? They went back to the distributor who put them back on the shelf and sold them to other people. Biggest example was the old GE 6550s where after a while, all Richardson had on its shelves were quadruple rejects from companies. No worries because they continued to pass them off as good tubes.

If you talk to C-J, their top requirements for selecting a tube is reliability and durability (which are different measures of quality).
