There may not be a solid answer for you about tube life. All depend on how often it is used during daily listening. For those preamp tubes with low power consumption, they could last few years during normal use. My unit has been in use 300 hrs since then.
Upon delivery of my c2300, I replaced the line stage pair with Gold Lions reissue 12ax7 gold pin(hk$500, other may cost less). I leave those 4 stock tubes in for the phono section, because I dont listen to vinyl much
Yes, those stock tubes with Mcintosh name are made in China, but in quality built, indeed they sound great to me with exception of little noisy when compare to the GLs. However, for tube rolling, it wont cost much though. Hope this helps. |
