Tube rolling can be fun and make you a little crazy at times. Both input and output tubes make a difference. For me the output tubes have a greater effect. But they are usually more expensive.
Tube Rolling -Input vs. Output tubes
I was hoping to hear what other people's experiences are here. I've got a Cary V12r. Until today I had all the stock tubes in it, which is the 12 Ruby EL34, 2 new issue Electro-Harmonix EL84, and two GE 12BZ7 tubes. I've been contemplating rolling the power tubes, but was being cheap. (cheap vs. hi-fi - the never ending conflict) Today I was at my secret purveyor of old tubes and I got two NOS EL84s, labeled "Hammond" presumably for an organ, labeled "Made in England" and two NOS RCA 12BZ7. Installing the EL84s first made a discernible difference in the sound - quieter background, more definition to the instrument image, and more defined, tuneful bass. Anyone else have thoughts on the impact of input vs. output tubes on an amp's sound?
