User manual FENDER TONE MASTER

[. . . ] The Tone-Master is a hand-made, point-to-point wired, tube instrument amplifier. There are no solidstate (transistor) devices in the signal path of any kind. [. . . ] NEVER use a fuse of higher current rating as this could damage the equipment and present a serious safety hazard. If the amplifier repeatedly blows fuses, it should be checked out by an authorized Fender service center. In the STANDBY position, the amplifier is off, although power is applied to the tube filaments to keep them warmed up and ready to play. A good rule of thumb is to turn the power switch on and wait at least 50 seconds before turning on the standby switch. One, to set the output impedance of the amplifier to best match the speaker impedance for maximum power. Second, to enable the amplifier to better achieve the cranked-up sound at a lower volume. On the B CHANNEL, with a single Tone-Master enclosure, this switch should be set according to the setting of the B CHANNEL volume knob: For volume settings of 3. 5 and lower, LO would be the appropriate setting. This switch will not damage tubes or reduce tube life at these settings. What it does do is increase the gain in the LO and MED settings and thereby better approximate the Full volume sound at a lower level than by adjusting the VOLUME alone. With a single 16 enclosure, LO will produce 30 watts, MED will Produce 60 watts, and HI will produce a full 100 watts. With two 16 enclosures, (an 8 load), LO will produce 60 watts, and MED will Produce 100 watts. In the A CHANNEL, the switch has the same function, although blues players may like running the switch on LO all the time to get that great crying tone. Conversely, a player looking for a New Wave Strat® tone might like the sound of the A CHANNEL on HI. This jack must be used as the primary connection for speakers. F. EXTERNAL SPEAKER - Plug in connection for an external speaker. [. . . ] If, after checking all of the above, the system is not performing correctly, consult your Fender authorized service center.
