I think Gluke is right about the the brown wire and the way it is cascaded.
Once the 1959RR was released, I tried to find the owner's manual on the internet but no luck.
I couldn't find the English version of the 1959RR handbook, but at some point (don't know when) I did find a Japanase version.
It's on the Japanese Marshall website:
I copied the Japanese text from the PDF into Google Translate to translate the Japanese text into English, with quite a cryptic text as result:
[color=darkred]1959 RR rear panel front panel 1959RR
1. Power switch
Amplifier and power on / off switch. Power amplifier with the appropriate power supply That when the switch is illuminated. Amplifier is turned off when the power is supplied by When he is not illuminated.
NOTE: When you move amplifier, power amplifier to cut the power cord pulled out state ARUKO And please be sure to check.
2. Standby switch
Switch to standby power switch (1) in conjunction with the amplifier to warm up before use Can be life-power tube can be extended. When you use amplifiers, Make sure you switch the power at the standby switch to "standby" remains the . The vacuum tube to warm the supply voltage is needed. Approximately two minutes later, the vacuum tube
Temperatures reached the correct behavior, you can switch on standby. Playing??
Amplifiers expected to be on / off when the vacuum tube to extend the life of the standby switching Ji use only, please. Also, completely off the power when the power switch off before the News
By Tan please switch it off.
NOTE: The following Presence (4), bass (5), middle (6), Treble (7) after completing four Troll, Channel 1 and Channel 2 all common to both. Treble, middle, nyah Su is very interactive, one to control and manipulate the other two control Le action may change. Try out a variety of settings, it is recommended. Randy's favorite setting is on the panel as well.
3. Control Presence
1959 RR is the power of the control section of the action, power amplifier NEGATI By changing the feedback in a high-frequency sound to increase. Clockwise And sound and turn a piece of "Art" is increasing, from Sharp and Crisp.
4. Based Control
Adjust the bass sound. Clockwise turn will increase the range and bass.
5. Middleware Control
The most important mid-range sound regulation. Clockwise around mid tones and increasing the thickness Oh Have heard the sound of the punch. And anti-clockwise turn, thus reducing the mid tones.
6. Treble Control
Adjust treble sound. And clockwise around high-frequency sound (Treble) will increase, Brighter tone guitar.
The 1959 Marshall Super Lead standard amplifier, unlike Randy Rose
L mode, the gain to increase, thus making the circuit to increase the distortion The changes have been made. This modification of the music that you had Randy distortion Amplifier to boost the level it is easy to use.
This change is very simple, but two separate valves to a "cascade"
(In the first stage output to send to enter the second stage) and the technique has been used Masu. Traditionally, each part is divided into two channels 1 and Channel 2 input buffer / GEINSUTEJI role of the first flag. Then take the next stage to supply the individual The signals are mixed in, and amplified by the tone stack supply.
Cascaded valves 1, the guitar signal is about 36 dB, or 60 times the normal circuit At this point, much larger than levels seen in amplification. This is the big signal After further amplified by the stage and soon became head room can be eliminated, resulting in the wave
Is a major form of distortion. The reshuffle also added another two-channel volume Does work, but the impact of change in tone, gain and increase the volume controls Roll. Channel 2, using the guitar signal cascade through the entire circuit Characteristic. Channel 1, using the cascade to bypass the standard amplifier Format. In this case, "Volume 1" is functioning normally. This Modification of the standard two-channel format is no longer available.
7. Volume 1
Channel 1's overall output level of regulation. Clockwise around the size and volume Com. This channel is a high sensitivity of the Treble.
Full cascade mode, the valve is Volume 1 of 1 amplified by the second half of the amount of signal Control the master volume as a whole cascade circuit. The PURIAN The next group stage to boost the signal sent to gain control and think about this And. Channel 1 is connected to the standard guitar mode, the normal cycle DIFAI 1959 Super Lead is not the same as the volume control Functional.
8. Volume 2
Adjust the full cascade mode. 1 valve amplified by the first half, supplied by the late The amount of signal control, by itself gain control circuit as a cascade.
9. Channels for a high-sensitivity input
Channel 1 from the bright sound of the "sensitive" guitar input, modified by TEI standard mode l does not generally the most commonly used input. Always high Quality shielded cables to be used for guitar please. NOTE: This input to connect the KASUKE DE bypass circuit in the amplifier is a standard format.
10. Channels for a low-input
Channel 1 for "low sensitivity" guitar input. "Sensitive" input from low-volume is 6 dB And (half) level, and the result, the ability to gain a small state. This is a non - Sensitivity is always active and high output pickup equipped guitar circuit is necessary to field May result. NOTE: This input to connect the cascade circuits are bypassed by the amplifier is based
11.'s Channel 2 input for high sensitivity
This guitar is connected to the input of a full cascade mode.
12. Channels for low-input 2
This guitar is connected to the input of a full cascade mode. "Sensitive" input.
Resona 6 dB volume is low (half) level, and the result is less ability to gain state. This is a very sensitive and high output active pickups are equipped with circuit The guitar may be necessary.
1. Loudspeaker output
Warning! The amplifier, speakers, please do not use any connection.
Speaker extension to connect to the cabinet two parallel Roud
Jack speaker output. Always a positive amplifier output impedance selector Please set properly (2). Also, make sure that high-quality speakers for the (Shield) Cave Please use the LE. Guitar (shielded) cable, please never put on the shelf.
When using extension cabinet, make sure to seal high-quality speakers
- No, please use the cable.
2. Output impedance selector
Speaker amplifier output impedance match.
Output impedance selector is set to change when, at 1959 RR always turn the computer A trim, please.
Marshall's all-valve amplifiers when using the following in mind, please. a)
During the operation amplifier must be connected to the speaker. b) amplifier selected INPIDAN News of the extension speaker cabinet and out of the total impedance Them.
