The base of the Captain M18 amp contains two switchable channels, with the first channel covering all sounds from clean to powerful crunch.
The second channel serves all sound wishes up to the fat rock board.
Channel 1: pure 18 watt sound with Tone and Volume (like the original)
Channel 2: JTM Sound with (ample) Gain, Treble, Middle, Bass and Volume (PPIMV)
HI: Silicon Rectifier and high voltage for punchy rock sound
Lo: Tube Rectifier and low voltage for creamy blues sound
Reverb for both channels (switchable via footswitch)
Captain Power Soak (switchable by foot switch)
For the full rock board at room volume. This makes the M18RP suitable as a bedroom amp.
And in live mode you have two volume levels available via footswitch (solo boost)
Parallel Send/Return (all Tube)
The power amp produces 18 or 20 watts from two EL84 power tubes, depending on the Hi/StBy/Lo switch.
As with the original, a GZ81 is used as the rectifier tube.
The output transformer is from Mercury Magnetics, the power transformer we have specially made.
The amplifier is built in all-tube technology and has no semiconductors in the signal path. Channel switching and all other switching functions are performed with high-quality relays and not with optocouplers.
The output transformer provides two output impedances (8 and 16 ohms), which can be switched by a switch on the rear panel.
