The 9200:
Double monoblock 100W per channel, each mounted double push / pull EL34 or 5881 in the models.
The following description will be for one channel, knowing that two-piece, his twin brother, well he has the same characteristics
For lamps, there is a 12AX7/ECC83 input and a phase shifter and 4x 12AT7/ECC81 in 5881 for the power section.
Level connection: 1 hall, 1 link (to connect the input of another amp, sometimes it Do not be enough power like that ...), 2 HP switch with 16 ohms / 8 ohms
The settings are reduced to their minimum gain and presence. With the ability to operate in two modes A / B, all remote controlled.
A ring mode "plexi" fat. Mode B sounds "modern" with the brightness and beautiful harmonics

UTILIZATION

Configuration is very simple, wiring in record time.
As for sound ... you branches, you go up the volume and you play!
No need for manual to understand how it works. Simplicity.

SOUNDS

Cut to be comfortable for all that has an affiliation with the rock, the rock'n'drôle néometal. Is obtained by method A or B or crystalline fat sounds. With JMP1, it opens the full range of Marshall.
It also has a connotation of "American" in the sound, as it is mounted in 5881.

OVERALL OPINION

I use it for several years now. He saw beautiful, and he never let go.
One small problem: his weight close to 35 kg.
The relamping costs between 70 and 80 euros per channel.
