Marshall AVT - Tube Warmth Meets Solid-State Convenience!
A Marshall AVT amp emulates the tone, feel and response of their world-renowned, all-valve amplifiers with unerring accuracy - without using valves in the power stage! The Marshall AVT50H is a 50 watt, 2-channel head that is perfect for powering the the AVT412A and AVT412B extension cabinets! Marshall AVT50H at a Glance:
- 50-watt, 2-channel head with features to spare!
- The warmth of valves with the convenience of solid-state
- Musical AVT power stage
I'm new to these forums, but I got here via Google, because for a while I am searching for schematics of Marshall AVT amps. I'm mainly very interested in how they designed the preamp with the 12AX7-valve. I was wondering if you would send me the schematic mentioned in this thread (or any other AVT). Greetings from the Netherlands, Mark.
Marshall AVT50H - Features for Studio & Stage If you have heard that 50 watts of solid state power is not loud enough to gig with, listen again. The AVT50H has two footswitchable channels for glistening clean tones and a roaring crunch that just oozes vintage authenticity. Crank the Overdrive channel's Gain control to the max and you have a contemporary high gain sound that packs an unbelievable punch, staying tight and focused thanks to the carefully designed closed back cabinet. Tube Warmth & Solid-State Convenience Meets Digital Power In Marshall's quest to give players the ultimate tone at an unbelievable price, they have combined the latest innovations in valve, solid state and digital technologies to achieve optimum sonic performance in the AVT line of amps. Valve Drive Pre-amp Every Marshall amp in the AVT line, including the Marshall AVT50H, boasts a pre-amp stage that is driven by an ECC83 Dual Triode valve. Unlike other hybrid amps out there, this valve isn't merely acting as a pilot light. Instead it is playing the central role in the gain, distortion and tone generating circuitry. Marshall has gone to great lengths to ensure that this precious device delivers maximum sonic benefit at all settings and volume levels. The resulting clean sounds ring with the bell-like harmonics that only a valve pre-amp can deliver and the break-up is never harsh or unnatural sounding. Whenever you select an AVT Overdrive channel, the ECC83 is saturated to its limit, providing dynamics and feel worthy of a place in the Marshall hall of fame. Power Amp Delivery The same, unrivalled design expertise that went into the pre-amp was also channelled into the design of the AVT power stage. Using frequency dependent power amp damping and Marshall's proprietary, dynamic clip level technology (which emulates the HT supply of a valve power amp), each AVT power stage creates the warm, musical feel and 3-dimensional sounds that have made Marshall's all-valve power amps world-renowned. Also all Marshall AVT products, including the Marshall AVT50H, will deliver the goods in the often hostile and unpredictable environment of the live performance stage. Marshall AVT50H Features:

Straight Marshall Cabinet For the AVT Series!
The Marshall AVT412XB is a purpose-built straight 4x12', 200-Watt, Celestion loaded cabinet. The AVT412B's purpose is to be used with any of the ATV series heads! Those include:
A Marshall-Celestion collaboration Knowing the importance of the relationship between power amplifiers and loudspeakers, Marshall has worked extremely closely with Celestion to develop a range of speakers that will re-define the cutting edge in rock guitar reproduction. Extended response loudspeakers The 412XB cab (straight) is a 200-watt cabinet, loaded with Celestion speakers. The slightly larger cabinet size lowers the cabinet's resonant frequency, giving even more bass response (Great for drop tunings and baritone guitars). Even though the traditional Marshall half-stack is a head and an 'A' cabinet (Jim Marshall thought it looked better), many guitarists are choosing a 'B' cabinet for the lower frequency response and the focused throw of the speakers. In many onstage full stacks, the top 'A' cabinet is often not plugged in.
