SLAVE, 4ohm, 4ohm, 8ohm, HT FUSE and Power Cord Input with fuse tray.
Mondo Transformers placed up front and propper. 6L6 Valves with 2 12AX7's

Straight forward and basic chassis outlay on top, makes for easy design layout
under the hood of the chassis. Roll bar construction originating from early
Mat Mathias design of GT style Matamp's. This roll bar construction is unique
and done correct, as only seen on original Mat Mathias built amps. Notice how
the knobs/pots are not at risk when the amp is on it's front. Also, the roll bar
serves as a support cage preventing the tubes from touching when the amp
is upside down being serviced.
It true Artisan Craftmanship, Signed & Dated September 1, 1999, Serial #12.
The ORANGE AD140B Hardwire Unit is pure. When you turn the
amp on, the power light takes a moment to glow. At a full glow,
the amp is incredibly silent. No frequency humm or buzz at all.
Turning the volume up, the amp remains silent. Punchy full bass
tones burl from this amp unit. The SLAVE OUT jack in the back
of the amp is being utilized in the photo above. This allows the
EQ from the AD140 to be shared with the additional power provided
from the ORANGE Matamp SLAVE 200 that drives 4-15" speakers.
The ORANGE AD140B drives the 8-10 in good fashion @4 ohm.
The amp really sounded supper through a single 2X15 @8ohm.
The amp has strong clean tones with the stock 6L6 Valves and
a partial distorted tone at full volume. It holds solid and stable
for good punchy bass. With EL34's, the tone heats up the distortion
and you have a brighter voice, with overdrive that can let you do
a wider range of distortion. For kicks I ran a set of 6550's with
the voltage around .35volts per socket. Burly fat bass tones
with a ripping distortion came from the unit. The space between
the glass is too close, so I don't recommend this tube for
