Changing Tubes in the MA 252?
Hello MAC experts.
As one who likes to tinker,I'm considering changing out the stock tubes on my MA252 integrated amp. it has a pair of 12AX7a tubes and two 12AT7 tubes My questions are: would there be any advantage in terms of sound enhancement? Would the color of the tubes after warm up remain green or another color? Thanks! Gabe |

It's not the tubes that are glowing green, it's the LEDs that are below them that you're seeing. New tubes would still appear green and then amber if driven into overload.

Tube rolling is quite popular and can be part of the appeal of tube gear. You can go from the Gold Lion reissues to crazy priced 1950s NOS tubes. The GLs are popular choices here, I'm not sure which OEM tubes Mc is using these days.

I believe that McIntosh uses Russian (New Sensor) tubes in their equipment these days.

First off, what "sources" are you referring to? Secondly, what company is producing tubes in the US?

I am unaware of any US made receiving tubes.

I am also unaware of any US company producing vacuum tubes.

The on line source I used obviously was wrong stating the tubes were of American origin. I ordered some Gold Lions and will try them... Gabor |

Please report back with your findings because I also have an MA252.
