Check Grant Fidelity - Psvane Treasure high-grade tubes. I use them in my C2300. I have tried Mullards, Teles (ribbed), Gold Lion, Mazda, Sovtek LPS, etc. The Psvanes have won.
McIntosh C 220 Pre amp tubes...
Wondering when I should replace my C 220 pre tubes. They have roughly 1000 or better hours on them. Has anyone replaced them before in theirs, and are they easy to do under the Mac hood? Any brand recommendations for 12AX7a replacement tubes for it? Don't know what brands are good, and open to suggestions/ideas. How long do preamp tubes last on average?
Thanks in advance for any input!
