Kevin......Yes and no. By that I mean yes, I knew the new amps were on the way and I wanted to ensure the C2300 performance wasn't being held back by weak tubes. The no part of the answer is I normally have an annual schedule for preventative maintenance that I usually perform each year in June. I was lax this year and let June, July, and August slid by without doing my due diligence. This has been a tough year for me. Here it is September already, so the arrival of the MC75's triggered me to get in gear.
When I perform my annual tube testing I keep records of each tube's numbers, i.e. transconductance, gain, and in the case of the small tubes, noise. That way when next year's tests are done I can refer back to the previous year's numbers for reference. I also test and record the information on all new tubes purchased, again as a reference point for testing annually once new tubes are put in service. I also test new tubes to ensure that when I pay for matched tubes they actually are matched. I have found a couple instances where one out of four matched tubes was way off the mark. I buy from reputable tube venders so getting a replacement happens without an issue. Like everything else, some things require specialized tools. Owning tube preamplifiers and tube power amplifiers practically demands that a tube tester be available.

C2300 Motivation
My dealer frequently asks why I don't "upgrade" my 7-8 year old C2300. Besides the extremely quiet operation, multiple balanced inputs that exceed current models, and the ability to upgrade peripheral components around it< I can never see a reason to trade up(?). Besides, my investment in premium XLR cables is substantial!
Still running with my original tubes............your suggestions for a supplier would be appreciated. (Cryo?) My Anniversary twin MC275's need tube swaps too. Thanks for making me love my C2300 even more. |

Bruce.......I'm with you on the love of the C2300 preamplifier. In my opinion the C2300 is a superb analog tube preamplifier. It does everything I want it to do and then some. The operating features never get in the way of the sonic performance, and it sounds so good. I don't see myself parting with my C2300. Your dealer is just trying to feather his own bed with the sales pitches about your "old" preamp.
Tube venders I use are TubeMonger.com, TubeDepot.com, TheTubeStore.com among others. SweetWater.com sells 12AX7 tubes, and so does Amazon.
