Your 3RD POWER Amplifier is a professional musical instrument amplifier. The information 
contained herein is current at the time of publication. However, specifications are subject to 
change without prior notice.

PRECAUTIONS & WARNINGS

READ THESE INSTRUCTIONS.

KEEP THESE INSTRUCTIONS.

HEED ALL WARNINGS.

FOLLOW ALL INSTRUCTIONS.

YOUR AMPLIFIER IS LOUD! 
EXPOSURE TO HIGH SOUND VOLUMES MAY CAUSE PERMANENT HEARING DAMAGE ! 
Practice “safe listening.”

No user serviceable parts inside. Refer service to qualified personnel. Always unplug AC 
power before removing chassis.

IF YOU INTEND ON OPERATING THIS EQUIPMENT OUTSIDE OF THE USA: Always insure 
that unit is wired for proper voltage. Make certain all connections and grounding 
conforms with local standards. Make certain that you have obtained authorization to 
operate prior to connecting to power supply.

WARNING: Vacuum tube amplifiers generate heat. To insure proper ventilation always 
make certain there is at least four inches (100mm) of space behind the rear of the 
amplifier cabinet.

Keep away from curtains or any flammable objects.

WARNING: Do not block any ventilation openings on the rear or top of the amplifier. Do 
not impede ventilation by placing objects on top of the amplifier which extend past the 
rear edge of its cabinet.

WARNING: Do not expose the amplifier to rain, moisture, dripping or splashing water. Do 
not place objects filled with liquids on or nearby the amplifier.

WARNING: Always make certain proper load is connected before operating the amplifier. 
Failure to do so could pose a shock hazard and may result in damage to the amplifier.

Do not expose amplifier to direct sunlight or extremely high temperatures.

Always insure that amplifier is properly grounded. Always unplug AC power cord before 
changing fuse or any tubes. When replacing fuse, use only same type and rating.

Avoid direct contact with heated tubes. Keep amplifier away from children.

Be sure to connect to an AC power supply that meets the power supply specifications 
listed on the rear of the unit. Remove the power plug from the AC mains socket if the unit 
is to be stored for an extended period of time. If there is any danger of lightning occurring 
nearby, remove the power plug from the wall socket in advance.

To avoid damaging your speakers and other music equipment, turn off the power of all 
related equipment before making the connections.

Do not use excessive force in handling control buttons, switches and controls. Do not 
use solvents such as benzene or paint thinner to clean the unit. Wipe off the exterior with 
soft cloth.

Preparing to Operate your Wooly Coats™ Spanky MKII Amplifier

Make certain that all connections are made prior to operating your Amplifier including power cable, 
speaker connection, instrument cable and instrument connection. Make certain that all tubes are 
installed.

Power Switch (1)

The POWER switch, when placed in the UP position, provides AC wall power to the amplifier.

Standby Switch (2) 

The STANDBY switch, when placed in the DOWN position, puts the amplifier in ‘standby mode’ 
allowing the tubes to warm up. When this switch is place in the UP position, the tube circuitry is fully 
functional and ready to amplify your guitar signal.

AC Input (11)

The AC INPUT socket (TYPE IEC Grounded) is a required connection for operating the unit at 120V 
(standard USA household electrical power). 

Mains Fuse (12)

The MAINS FUSE requires a 1.25 AMP slow-blow fuse. This fuse protects your amplifier from voltage 
peaks from your power outlet.  

H.T. Fuse (13)

The H.T. FUSE requires a .25 AMP (250 milliamp) slow-blow fuse. The H.T. FUSE usually blows if your 
power tubes are bad to protect the circuit from being damaged. 

SAFETY NOTES:

• Always plug your amp into a properly grounded 3 prong AC outlet. 
• Never plug your amp into an ungrounded outlet. 
• Never remove or break off the 3rd prong safety ground pin from the power cord. 
• Never use a damaged or ungrounded power cord.
• Always use the proper value and type fuse according to the rear-panel markings.
• Never attempt to replace the fuse while the amplifier is still plugged into the power source. The 

fuse should only be replaced when the power cord has been disconnected from its power source.

8-OHM Speaker Output (14)

The Wooly Coats Spanky model has been designed to give you the greatest amount of flexibility 
when operating your amplifier. Now you can choose the correct speaker output impedance for your 
situation. Connect the internal speaker to the 8-OHM when operating only the internal speaker. .

4-OHM Speaker Outputs (15)

The 4-OHM SPEAKER OUTPUTS are wired in parallel. They are provided for connecting your 
amplifier to a single 4-OHM speaker, or two 8-OHM speaker cabinets, or more traditionally, a remote 
speaker cabinet that is connected simultaneously with the internal speaker.

SAFETY NOTES:

• Never operate your amplifier without a connected speaker cabinet. This will damage your tubes 

or transformers - or both. 

• Always operate your amplifier with the proper impedance output that matches your speaker 

cabinets(s). 

• In all cases, always use a good quality heavy gauge speaker cable (not a shielded instrument 

cable) to connect your guitar amplifier to the internal speaker or external speaker cabinet(s).

Foot Switch Jack (16)

The FOOT SWITCH jack is provided so that you can turn the onboard effect(s) on and off as desired. 
In the reverb-only version, this jack is a standard “tip/sleeve” configuration. In the reverb + tremolo 
version, this jack is configured as a “tip/ring/sleeve” allowing control of both effects. 

To Tank Reverb Connection (17)

This RCA jack connection is provide to send the amplifier signal to the reverb tank. 

From Tank Reverb Connection (18)

This RCA jack connection is provide to receive the return signal from the reverb tank. 

OPERATION NOTES:

• To avoid unnecessary noise, please make sure that you use a standard “shielded” guitar cable for 

the reverb-only foot-switch connection.

• To avoid unnecessary noise, please make sure that you use a “shielded” TRS cable for the reverb 

+ tremolo foot-switch connection.

• Please make sure that the reverb send and return are connected with proper orientation and 

that you are using shielded RCA wire connections.

Tube Layout and Requirements:

V1 and V2: JJ 12AX7 (Preamp)
V3 and V4: Sovtek 12AX7LPS (Reverb and Phase Inverter)
V5 and V6: JJ 6V6 output tubes
V7: JJ 5AR4 Rectifier tube

Bias Adjustment

Your Wooly Coats Spanky Amp comes from the factory biased at 24ma idle current for JJ 6V6 tubes. 
Bias adjustments are not intended to be user-serviceable. Attempting to adjust the bias yourself will 
expose you to very dangerous high-voltage electricity that can kill you. Special test equipment and 
knowledge of amp circuits and tubes are required to perform this function. DO NOT ATTEMPT TO DO 
THIS YOURSELF. 

Tube Replacement

WE RECOMMEND TAKING YOUR AMPLIFIER TO A QUALIFIED TECHNICIAN FOR SERVICING YOUR 
TUBES. Make certain the amplifier is turned off and has been allowed ample time to cool down. Be 
very careful when you remove the tubes as they might still be very hot! Do not touch tube sockets 
with fingers! Even after turning your amp off and unplugging it from the power outlet there could be 
enough voltage stored in the capacitors to give you a lethal electrical shock. 

WARNING:

• Do not remove the back panel.
• Do not attempt to check or replace tubes yourself. Refer to an authorized service center. 
• Never touch the tubes while the amplifier is turned on or has recently been turned ON. You can 

severely burn your fingers and hands.
