Default C2300 Tube Test Day

I test my tubes in my gear once a year, usually in June. I have been a bit lax this year, but today I managed to motivate myself into pulling the C2300 out of the living room rack and testing the 12AX7 tubes in the line stage and moving coil phono stage. I have Gold Lion ECC83/12AX7 tubes in the line stage and Telefunken ECC83/12AX7 tubes in the moving coil phono stage. My tube tester for small tubes is the Maxi-Preamp 2 from Maxi-Test. After 15 months daily use of the C2300, both pairs of 12AX7's still tested strong and closely matched. No reason to install new tubes at this time. That's good news. I reinstalled the tubes in the preamp, and reinstalled the preamp in the rack. I love my C2300 preamplifier. It's feature rich, quiet as a mouse, sounds remarkable, built like a tank, and is all analog.
