BIAS.

As with all MESA/Boogie amplifiers, the bias is permanently set during construction and never needs adjustment. This saves you any technician's fee for readjustment when replacing tubes, and prevents the bias from "wandering" or being accidentally set improperly.

DRIVER TUBES.

The four small tubes are all type 12AX7A, also known as 7025 or ECC83. These tubes are very long-lasting and trouble free in the 295; should they ever need replacement due to a specific malfunction, genuine MESA replacements are recommended for best performance.

The input stage of your 295 uses a special "instrumentation grade" differential amplifier with

aproprietary constant-current-source diode. This is a high-tech little solid-state component which enables the phase splitter to work in a simple, self-balancing mode - one of the keys to great performance. Occasionally a certain 12AX7 will not quite match this device and one channel will sound weak as a result. Merely try another tube, or exchange it with the one next to it. Generally though, our experience with the various MESA predecessors of Your 295 indicates that you should enjoy many years of trouble-free service.

Now that you've had this brief explanation of its functions and features, it's probably time to plug up! We think you'll be pleased with the sound of your 295 - so enjoy it and enjoy your music!
