AMPLIFIER SPECIFICATION Caiman 5300 is a full tube head amplifier, hand crafted by qualified craftsman. This amp weighs not even 15 kilos and still has 50 Watts of power. The design of the amp, solves the permanent problem of every musician - the handling. It is not only light weigh tube amp, but also it’s all integrated in a very compact housing. With its soft and compressed sound, it is the ideal amp for all ranges from Blues to Metal, offering the comfort a musician is used to and expects from an amp.
AMPLIFIER FEATURES - power: 50W, - tubes used: 4 × EL84, 2 × 12AX7, - speaker (combo only): Celestion G12T-75, - two channels: clean and distorted, - volume control: clean channel, gain and volume controls – distorted channel, - two separately gain knobs controlled with a footswitch: Gain1 and Gain2, - the same tone control for both channels, - footswitch: changes channels and switches between Gain 1 and Gain 2, - channel switching on relays, - separate Bright switches for both channels, - series effects lo
SAFETY PRECAUTIONS ATTENTION: To reduce the risk of electrical shock, do not remove the back cover of the amplifier. Inside parts can be repaired only by qualified service personnel. WARNING: To prevent the risk of electrical shock do not expose this appliance to moisture, rain or any liquid. This symbol is intended to alert the user to the presence of dangerous voltage and constitutes a risk of electrical shock.
TECHNICAL HINTS, PROPER USAGE • avoid using the amplifier in humid and dusty places • do not put it in an unstable place • do not install the apparatus near any heat sources • do not use the amplifier before connecting it to the correct cabinet • after switching on, wait about 30-60 seconds until tubes get heated • switch the amplifier off before any cable change • in order to ensure proper air circulation, do not block any of the ventilation openings • never put any liquid containers near th

1. Channel selection Switch to change channels of the amplifier. It works only when Jack is unplugged from the Footswitch socket. In position “up” the clean channel is on, whereas, in position “down” the distorted channel is on. 2. Footswitch Socket to connect a footswitch, with controlled Channel switching and Gain selecting. TRS Jack socket (T – tip:1, R – ring: 2, S – sleeve: 3), where tip changes channels, ring changes masters, sleeve is ground.
. Bass Adjusts the low-frequency tone for both channels. 11. Middle Adjusts the middle-frequency tone for both channels. 12. Treble Adjusts the high-frequency tone for both channels. HINT: Set all the potentiometers in a 12.00 o’clock position, then adjust them individually to get the best sound. Remember, that the frequencies of each controller are related to each other, the change of one influences the others. 13. Master Volume Master volume control.
REAR PANEL Combo: Head: 1. Main fuse integrated with power supply socket Ma Sp are fus e in f u se Slo Blo fuse T1.25A is in the case, integrated with power supply socket. There is one spare fuse inside. HINT: Take out the power cord during a storm or when unused for a longer period of time. HINT: While changing the fuse , make sure the blades of the fuse are properly installed.
3. Effects loop socket - “Send” Output signal socket taken from the preamplifier. Nominal signal output level is 0dBV. ATTENTION! Do not connect the cabinets with different impedance at the same time. ATTENTION! Before turning the amplifier on, make sure the cabinet is connected to the appropriate power output socket. HINT: This output always has signal, even if the loop is not used. Consequently, the outlet can be used to connect a guitar tuner permanently – it does not influence the sound. 4.
Hints concerning tubes Leave tube change and bias setting for qualified personnel. Tubes could get heated intensively. If you touch them, you can get burnt. That is why, before you change tubes, turn amplifier off, take the plug out and wait for them to cool down. Before you change tubes, pay attention if their “feet” are straight because the feet have to be positioned in a certain way. The first symptom that tubes should be replaced is worsening the tone of the amplifier.

TROUBLESHOOTING SYMPTOM RECOMMENDED INTERVENTION The amplifier doesn’t play, LED diodes aren’t lit, control light isn’t lit. Check if the main fuse isn’t blown or if the power supply cord isn’t broken (use another). If it still doesn’t help, contact Laboga service personnel or any Laboga retailer. There is smoke coming out of the amplifier. Immediately unplug the amplifier from the mains outlet and contact authorized Laboga service personnel or any Laboga retailer. Don’t repair it yourself.
While playing there are weird sounds – crackle, or the sounds vanish completely Check if the power cable is inserted properly and if it isn’t falling out of the socket. Additionally, check the quality of the speaker’s cable – if it isn’t damaged and if the cable has the proper diameter. The amplifier gives uncontrollable weird, loud sounds even if guitar is unplugged. Observe if it happens on both channels (this information can be crucial while consulting the service department).
