1. MAINS (POWER) SWITCH
This is the On/Off switch for the mains electric power to the amplifier.
Note: Please ensure the amplifier is switched off and unplugged from the mains electricity supply whenever it is moved!
2. STANDBY SWITCH
The Standby Switch is used in conjunction with the Power Switch (item 1) to ‘warm up’ the amplifier before use and to prolong the life of the output valves. When powering up the amplifier always engage the Power Switch (1) first, leaving the Standby switch on ‘Standby’. This enables the heater voltage, allowing the valves to come up to their correct operating temperature. After approximately two minutes the valves will have reached their correct operating temperature and the Standby Switch can be engaged, enabling the HT without ‘shocking’ cold valves. In order to prolong valve life, the Standby Switch alone should also be used to turn the amplifier on and off during breaks in a performance. Also, when switching off, always disengage the Standby Switch prior to the main Power Switch.
3. INDICATOR
This 6.3 Volt incandescent filament indicator will light up whenever the Super 100JH is plugged into the mains and the Mains Switch (1) is on.
4. PRESENCE CONTROL
This control affects high frequency content in the negative feedback derived from the Super 100JH’s power section and fed back to the phase inverter. Turning it clockwise adds an extra high cut to your sound.
5. BASS CONTROL
7 | 8 | 9 | 11 | 13 |
8. LOUDNESS 1
This controls the overall output level of Channel 1, turning it clockwise increases the volume. This channel is voiced for a higher treble response than the amp's other channel, Channel 2, hence its ‘High Treble’ labelling.
9. LOUDNESS 2
This controls the overall output level of Channel 2, turning it clockwise increases the volume level. This channel is voiced for a flatter, more ‘normal’ response and is labelled ‘Normal’ accordingly.
10.TOP (HIGH SENSITIVITY) INPUT FOR CHANNEL 1 This is the ‘high sensitivity’ guitar input for Channel 1, the High Treble channel. It is the most commonly used input.
Note: Always use a high quality screened guitar lead.
11.BOTTOM (LOW SENSITIVITY) INPUT FOR CHANNEL 1*
This is the ‘low sensitivity’ guitar input for Channel 1. Its sensitivity is configured to be 6dBr (decibels) lower than the channel’s ‘high sensitivity’ input.
*Note: There is photographic and film evidence that Jimi used this input rather than the high sensitivity input on certain occasions. A particularly famous example of this can be seen in the footage of his now legendary live performance of ‘Hey Joe’ and ‘Purple Haze’ at the Marquee Club, London, on March 2nd, 1967, for the TV show, Beat Club.

Performance Note: ‘Jumping’ the two channels and ‘Daisy Chaining’ amps.
Because both channels of the Super 100JH have the same number of gain stages and are in phase with each other, it is possible to ‘jump’ (a.k.a. ‘link’ or ‘bridge’) them together and use them both at the same time. Doing this enables you to expand upon the amp's tonal capabilities.
The most common way of doing this is to plug your guitar into the top input of Channel 1 and then run a short ‘jumper’ guitar cable (i.e. a screened cable) from Channel 1’s bottom input to the top input of Channel 2, (Fig. 1). Adjust Loudness 1 & 2 controls until the desired mix of tone is achieved.
The reverse is also possible, i.e. plugging your guitar into Channel 2’s top input and then running the ‘jumper’ cable from Channel 2’s bottom input to Channel 1’s top input (Fig. 2).
Whether the channels are linked or not is entirely the choice of the individual player’s taste in tone. As always, experimentation is the key.
It is possible to ‘Daisy Chain’ or Link a number of amplifiers together using the same principals described above. As illustrated in numerous photographs, Jimi would often use this facility to ‘split’ his guitar signal between two or more full stacks - his guitar would be plugged into the top input of Channel 1 on his main amp and then a relatively long ‘jumper’ cable went from the bottom input of the same channel to the top input of Channel 1 of the second amp.
1. OUTPUT IMPEDANCE SELECTOR
Matches the amplifier's output to the load (speaker) impedance.
Important Note: Your Super 100JH should be completely powered down before the Output Impedance Selector is turned.
It is imperative that: a) at least one of the speaker outputs of the amplifier is connected to a load whilst in operation and b) the impedance on the output selector matches the total impedance of the speaker cabinet(s) being used. The following combinations are our recommendations -
1x16 Ohm cabinet - Selector set to 16 Ohm
2x16 Ohm cabinets - Selector set to 8 Ohm
1x8 Ohm cabinet - Selector set to 8 Ohm
WARNING! Use of any other combination/configuration of cabinets and/or impedances may result in sub standard sound and possible damage to the amplifier and/or the speaker cabinet(s)
WARNING! Failure to comply with any of the points raised in this section may result in damage to the amplifier.
2. LOUDSPEAKER OUTPUTS
There are two parallel loudspeaker output jacks provided for connection to the speaker cabinets. Please always ensure that the amplifier’s output impedance selector is set correctly (see item 1) and ALWAYS ensure you use good quality, unscreened (unshielded) speaker cables for this purpose. NEVER use guitar (screened/shielded) cables.
WARNING! Never use the amplifier without a speaker load attached!

4. MAINS INPUT
Your amplifier is provided with a detachable mains (power) lead, which is connected here. Before connecting for the first time, please ensure that your amplifier’s mains selector (item 3) is set to your country’s domestic electricity supply voltage. If you have any doubt, please get advice from a qualified technician. Your Marshall dealer will be able to assist you.
Important Note: Always ensure that there is a (speaker) load attached before connecting the mains lead.
5. MAINS FUSE
The correct value of this MAINS fuse is specified on the rear panel of the amplifier. For safety reasons NEVER attempt to bypass the fuse or fit one of incorrect value.
6. H.T. FUSE
The correct value of this H.T. fuse is specified on the rear panel of the amplifier. For safety reasons NEVER attempt to bypass the fuse or fit one of incorrect value.
Note: In the original heads this fuse was mounted internally, making a quick change impossible and anything but convenient! For obvious reasons we have made it accessible via the rear panel.

Speaker Cabinet Features 1982AJH & 1982BJH 4x12" Cabinet Construction:
Note: The extra tall, straight fronted 1982BJH cabinet is 6 3/4" (173mm) taller than a regular Marshall 1960B cabinet.
4x12 Cabinet Cosmetics: The small, gold Marshall Script logo, ‘100’ corner logo, black Levant covering, leather strap handles (placed on the top of the 1982AJH and on the right hand side of the 1982BJH), gold beading, white piping and pinstripe grille cloth duplicate the look and style of the originals. To this end, the input jacks on both cabinets are placed near the bottom of the back panel. The original grey and white, pinstriped ‘Bluesbreaker’ grille cloth (used from 1965 to 1968) is no longer available, and wouldn't satisfy modern safety legislations regarding flammability because of its rubber content. Our supplier, ‘Somic Plc’ has worked with us to come up with a cosmetically similar, modern alternative.
Speakers: Both of these 100 Watt, mono, cabs are loaded with Celestion G12C 25 Watt Speakers which have been specially developed by Marshall and Celestion to duplicate the smooth, balanced sound of the original 25 Watt Greenback speakers found in authentic reference cabinets. In keeping with that time period, a black and gold Marshall label is on the back of the magnet cover, ensuring the look is as authentic as the sound.
