I have M60s built from kit in 1998 and have been using the same set of 12SX7s (V1 and V2)and 12SN7s (V3 and V4) since. I changed one set of 6AS7 a few years ago. Last night, I noticed hum in one amp. Normally how long do 6/12SN7s last? What is the plate voltage for the 6/12SN7s in M60? 12SX7 is rated maximal 300-volts. Thanks for your input. MP. |

Thank you, Ralph. Good to know. The 12sn7 tubes are Tungsol and GE (driver). |

It depend on how many wattage each tube they carry. |
