Replace only with same type and size. To remove the fuse, remove AC power cord and pull out on the tab above the fuse symbol located on the fuse carriage. Place the new fuse in the carriage clip and re-insert. NOTE: To prevent an electrical hazard, DO NOT replace fuse without using the fuse carriage. Replace the fuse carriage if lost or damaged before re-inserting the AC power cord. 2 & 3) Speaker Outputs—These 1.4” jacks are provided to connect the internal and/ or external speakers to the V50 amplifier. The V50 amplifier should never be operated without a speaker plugged into a speaker jack. 4) Impedance Selector—This switch is used to select the appropriate impedance, and is important in achieving the desired results from the V50 amplifiers. The correct impedance should be selected using the Impedance Selector Switch as follows: a. Internal speaker only: 16 ohm setting b. Internal speaker + external 16 ohm speaker: 8 ohm setting c. Internal speaker + external 8 ohm speaker: 4 ohm setting, although it’s not matched d. External 16 ohm speaker alone: 16 ohm setting Incorrectly “mismatching” the amp to the speaker should not damage the amplifier, but would result in lower output powers, and could result in shorter output tube life. 5) EL34 Output Tubes—These power tubes were selected to provide the best combination of performance and tube life, and shouldn’t require adjustment to their bias. The amp uses a mixed-bias system which is a combination of fixed and self-bias techniques to give the user the best of both worlds. The result is that the amp will control its own bias to a certain point, but without the typical reduction in power associated with normal self-biased amp designs. The V50 uses two EL34s in a “push-pull” amplifier configuration. 6) Phase Inverter Tube—The phase inverter tube uses a single 12AX7 in what’s called a long-tail pair configuration. This results in the most signal swing possible for driving a power amp, and the most symmetrical drive capability, as well. 7) Effects Loop/Boost Tube—The Defender amplifiers use an all-tube effects loop to preserve the tube sound through the signal path. This single tube is used for both the Effects Loop Send/Return and the footswitchable Volume Boost circuit. 8) Preamp Tube 2—This 12AX7 is used on both channels, but has the biggest impact to the lead channel since it has the additional stage required for the very large amount of gain. 9) Preamp Tube 1—This 12AX7 is the input tube, and as such, is the most likely to cause microphonic problems, especially in the lead channel, and it is also shared by both channels. If tube feedback occurs, it can usually be corrected by swapping this first tube with one of the other tube locations, since they have less gain following them and are less prone to feedback. The first tube also has the greatest affect on the “cleaned up” tone of the amp, i.e. the tone when the guitar is turned down. 1 367 18 19 V100 Front Panel 2 4 5 89101112 1) Input 1—This 1.4” input jack provides the highest gain through the amp. It is considered to be the “normal” input. 2) Input 2—This 1.4” input jack provides 6dB lower gain through the amp, so it will allow for a cleaner sound. It can also be useful when using pedals in front of the amp, since it provides more headroom through the front end. If a guitar is plugged into both inputs, then they will mix together and will both be 6dB lower in gain. 3) Rhythm Indicator—the word “Rhythm” lights up when the Rhythm channel is active. 4) Rhythm Volume/Pull Bright—The Rhythm Volume control adjusts the gain at the input of the amplifier when the Rhythm channel is active. It is used in conjunction with the Rhythm Master to adjust the amount of distortion and volume for the channel. For cleaner sounds, this control would be set to lower settings and the Master set higher. For slight breakup, the controls would be set in their middle ranges. For heavier distortion, set the Rhythm Volume higher and the Master lower. Pulling the Pull Bright will increase the high frequencies of the signal, while also reducing low frequencies for a chunkier, tighter attack. This function is very useful for fine-tuning the amp’s tone and feel for different guitars. 1314 151617 20 5) Rhythm Master—The Rhythm Master sets the overall volume of the Rhythm channel, and can be used to balance the volumes between it and the Lead channel. The inclusion of individual Master volumes for each channel means that the Rhythm channel of the V100 can be used for slight breakup sounds at lower volumes, rather than strictly being a “clean” channel. These settings are described in detail in the previous section entitled 4) Rhythm Volume/Pull Bright. 6) Channel Selector Switch—When the footswitch is NOT plugged into the footswitch jack, this switch allows the user to select either Rhythm or Lead channels on the V100. If the footswitch IS plugged in, it over-rides the front panel switch. 7) Lead Indicator—the word “Lead” lights up when the ...
